Credit cards also transfer wealth from people who pay interest to people who don’t.
It’s a silly system, where everyone has to invest their time (optimizing for rewards, avoiding interest) in an ultimately negative sum game. I hate it so much.

The intuition being: people who carry balances and pay interest don't actually spend very much; they are not wealthy.
2023: 79.5%
2024: 79.8%
2025: 80.2%
Capital One also is supposedly huge on car loans; I'd imagine the interest from those would comprise a big chunk of that revenue.
That's the interchange income corresponding to wealthy people. Interchange is paid by the card-accepting business, not by the buyer. The buyer pays interest and other fees and that graph looks very different.
From that original study the full picture table says in % of ADB that the "poorest" (below 620 FICO) pay ~45% interest and fees but bring only 2% additionally in interchange income. The wealthy (at 800+) pay ~10% interest and fees but bring another almost 10% interchange income, on 4 times higher spending, and 3 times higher rewards (so the wealthy get ~12 times higher rewards in $ value than the "poor").
Just the percentages paid by each group more than offset the difference in spending. There are also way more "poor" accounts than wealthy accounts. Intuitively you can tell that the banks are effectively subsidizing the fees and interest for the wealthy with the income from the poor, for the sake of the interchange income which is mostly generated by the wealthy but doesn't come from their pocket.
Those poorest of people (<620 FICO) pay more interest and fees (percentage and absolute terms) than any other group. There's a range in the middle on the wealth scale where the customers are actually a net loss for the banks (the 660-760 FICO range).
Agreed, which makes the picture even worse for those low income people. Even poor people are guaranteed to occasionally pay the "rich person tax" included in the prices of some of the products and services. At least until some AI pricing starts changing the price real-time based on the buyer's estimated wealth (sort of already real).
> So they are essentially is paid by the consumer.
Not from a bank's perspective. Only in the sense that prices are higher between the seller and buyer.
> If we outlawed rewards credit cards (by capping interchange fees), everything would likely be slightly cheaper.
I don't agree on the second point as a blanket statement. When Epic game store lowered its fee not a single game got cheaper for the buyers.
Credit card fees are baked into the price of everything that can be purchased with credit card, excluding merchants that offer a cash price and a credit price.
Any time someone pays the (credit card) price with cash or a debit card is paying more than someone that earns CC rewards, it’s virtually every transaction.
At least one reason for this is that Valve has language in their agreements to prevent you from selling your game cheaper on other storefronts. Unambiguously anti-competitive.
If I know I'm paying for my own rewards, I'd choose a card that keeps more money in my pocket. I'd go as low as the PITA factor of cash.
It's not clear to me what the net benefit is of a credit card over a debit card.
But for sure the confusion ensuing from allowing debit cards to be charged as credit cards should be illegal. The merchant account providers are probably the ones reaping the free money on the racket.
Credit is the POS default, for whatever reason. Not all POS are the same. e.g. US Post Office consistently knows if I am using a debit card, and it prompts for a PIN when I do. Every restaurant, bar, service does not ask for PIN, and the handful of merchants I've inquired with say their debit card fees changed by the merchant account providers are the same as credit. Scammy.
At least in Colorado it's legal for businesses regardless of the TOS contract with a merchant account supplier to pass on the transaction and processing fees of credit cards. It's not legal to pass on cost/fees for debit cards, ACH, or cash.
>It's not clear to me what the net benefit is of a credit card over a debit card.
In a fair scheme, the net benefit to the purchaser is having a rolling line of credit for whatever they want to use that for, like managing cashflow. It's also a benefit in that it puts a behemoth with immense contractual power between you and the merchant. It doesn't matter how a merchant fucks you over, the credit card company WILL give you your money back and punish the merchant.
To the merchant, the benefits are that credit cards unlock significant consumption that humans normally would not do. It literally causes induced demand. As a consumer, you will spend more money using a credit card, and you will purchase things you otherwise wouldn't. The disconnect in your brain is known. It can also, in very specific contexts, reduce the cost of managing payments and cash. It can reduce employee theft. But this improvement is overstated.
The reason merchants put up with giving away 3% of all revenue and eating $20 per fraudulent transaction plus whatever the cost of the transaction was is entirely about the fact that a consumer using a credit card buys more than one not using a credit card. It's a big boost to your revenue.
But there is absolutely nothing about a payment network that requires such transaction fees. Certainly not "Risk", as the credit card payment network itself carries zero risk on each transaction. Every dollar fraudulently spent comes out of the pocket of merchants, not the payment network. Their only risk is consumer default, but the entire "Credit Score" system exists to nearly eliminate that risk.
The structure of the system is built to get consumers to spend more money than they normally would, and incentivize everyone to play along to get a kickback. Everything in payment infrastructure in America is designed around this. Even gift card companies are built around getting you to spend money you were not intending to and kicking a portion of that back to the brand name on the card.
The most recent I've seen otherwise is this Federal Reserve study[0] from 2022. It finds that the marginal return on swipes is actually slightly negative because of how juicy rewards have gotten, and 80% of their profitability comes from interest (with most of the rest fees):
> we find that, on average, the credit function makes up approximately 80 percent of the credit card profitability, whereas the contribution of the transaction function is slightly negative, as rewards and other expenses on credit card transactions outpace banks' interchange revenues.5 In addition, fees—in particular late fees—comprise approximately 15 percent of credit card profitability.

Now I just use my apple card everywhere, pay it off every month and get whatever rewards I get.
It feels like a weird situation, those that stand to gain the most from credit cards are also the ones that should feel a difference of under $100 in rewards the least.
The one exception I see is bonus sign up rewards since those can be fairly significant, or making sure you use an airline card at the airline since those bonuses can be fairly significant (with sometimes other benefits). But outside of those exceptions, just choose a card with good rewards and stick with that and pay it off every month.
On the one hand, relative to our income it's not so important, but on the other it feels bad leaving $3k on the table.
So like, I have a card that's 6% on groceries, another that's 3% on gas and restaurants, Apple Card does 2% on Apple Pay transactions, and I have a 1.5% card for everything else.
The gain of a few thousand per annum is not worth the mental distraction.
It’s expensive to be poor. Higher interest rates, no credit card rewards, higher unit prices at places like Dollar General, etc.
You can just opt out of using credit cards.
I never understood why whole nation wants to live in debt just to have one extra month of cash flow (which they’ll probably squander soon).
Rational if you want a mortgage in the US at least.
Currently you're keeping money in the bank accruing the bank interest to occasionally pay for stuff.
With a credit card you would get various bonuses/cashback/gameified returns by owing them money, and it costs you nothing as long as you pay them back once a month interest free.
If you however slip up/miss a payment it will cost you a lot.
Both cases suck, but the latter saves you money if you play that game.
That's from a EU perspective. From a US perspective you also require it from a credit score perspective, which EU thankfully hasn't adopted... yet.

After 30 years, people generally speaking own their home and that's their biggest chunk of wealth. So basically, yes a high debt to income ratio, but it's building towards wealth and its not high interest debt either.
It is not, thus, free money, at all.
It can be done. The UK and the EU capped fees at 0.3% for credit cards and 0.2% for debit cards
I instead chose to live somewhere it's capped at 0.3% and then I don't have to fuck around to get my money back after the fact. As an added bonus, I don't even know what a medical bill looks like.
If I could get a debit card that gave me 2% cash back on all transactions, I'd use that instead!
For the consumer the reason is that this is revolving credit. If you pay next month you can have stuff today. That's a small relief, unless it turns into a carried balance and then it's an ongoing burden, but you don't think about that burden at first because you're naturally optimistic.
There is value in this even if you always pay your full statement balance every month.
If you have a stable source of income knowing your credit card payment is due on the 7th of every month means you don't have to monitor your checking account's balance for every purchase. You only have to think "make sure you can cover $X by the 7th".
That’s why businesses eat the credit card fees.
The reason is rather obvious, people spend more money with credit than they would’ve with cash. Accepting 95 cents on the dollar to get a sale with credit that you wouldn’t have got with cash still earns the seller money, money they wouldn’t have earned without accepting credit.
The entire credit card industry is set up to squeeze out as much profit from people as possible. They offer discounts as an incentive, but it is a huge trap that many, many people fall into. I'm not interested in risk. I'm interested in simplicity.
It's participating in the credit card industry that is foolish.
there is none. some people are just ideologically opposed to credit cards, like the parent appears to be.
their loss, really. they end up paying a portion of the cost but reap none of the benefits (rewards, additional legal protections)
Second, never use a card with an annual fee.
Third, which I already said, but bears repeating: pay off the full balance every month.
Fourth, look out for one good rewards card and funnel expenses through it, so you can get the rewards.
My parents taught me all of this 40 years ago, and it was exceptional advice, and has served me (and my family) very well.
Credit cards are not about carrying debt. They are the worst tool for that.
This is overselling it. You can come out 2% ahead or so. 4-5% if you are an extremely high spender who enjoys mentally managing 5 or 6 credit cards to max out category bonuses and other benefits and all that.
You come out marginally ahead at the expense of mental overhead. Good tradeoff for some, not for others.
I use a credit card, I dropped from 3-4 different cards trying to max out those 4-5% spending categories and just have a straight 2% cashback on everything card now. Plus one backup on a different payment network in case one goes down. It got to be exhausting trying to remember to manage so many cards plus remember to use the points, make sure to use the right card for the right thing, and all the other BS.
For some of my friends it's a hobby which is great for you if you enjoy such things! For me, it's just adding another chore to my life. Not worth the 1-2% or so marginal gain against my spending.
The super easy stuff is long gone these days too. You get far larger discounts paying via ACH for utility bills/cell phone bills/etc. vs. what credit card rewards give you so all the "autopilot" stuff is largely gone.
I do remember the days where we paid our Equinix bill via the company Amex. That was pretty fun while the party lasted!
Opting out doesn't save you from those costs.
I see many commercials for local banking up here that pulls out 30-40+ year members of the banks boasting about the prosperity the bank provided them, but at the same time, when they'd walked into the bank back in the day A Guy just said "yeah he's good for it" and wrote out the loans they needed.
You can't opt out of the modern credit scoring system and if you fuck it up even once with a bad line item you're out of the running for quite a few things and become virtually poor.
You can still implement “if I can’t afford something, I don’t buy it” with a cc. I pay mine off every month so it’s financially the same s a debit card but use a premium card for its purchase benefits.
I always get my money back when this happens with a credit card purchase. I've also had to dispute things occasionally, and I almost always get refunded.

> Industry body, UK Finance, estimates that criminals successfully stole £1.28 billion through banking fraud and scams in 2025. Of this, £703 million was unauthorised and £576 million was authorised.
> Unauthorised fraud is where the fraudulent transaction is carried out by a third party, not the victim. Authorised fraud involves the victim being tricked into paying money into another account that is controlled by a criminal. This is also known as Authorised Push Payment (APP) fraud.

> Frontier found that APP fraud losses have fallen by an estimated £73 million per year and the number of APP scams have fallen by nearly 35,000 due to the policy. Reimbursement rates for all claims have risen from 54% to 65%, and for claims in-scope of the policy, firms are now reimbursing 97%.
Anyway, the credit card companies (Diner’s Club and Bank Americard, now Visa but still retaining the original color scheme and logo) lobbied Congress in the late 60s to get these protections enshrined in law so that consumers would get a benefit over using cash as a positive incentive to switch.
These are available to Visa and Mastercard debit cards too.
But yeah, the UK has section 75 of the Consumer Credit Act.
actually it's better than a debit card, your purchases "float" for half a month on average you get to pay later. if you, as you should, maintain a regimen of always adding to your investment portfolio, this is a non negligible amount.
If you present a debit card to one of those desks, they may encourage you to swap for a credit card. Because a debit preauth ties up actual funds in your account. A credit preauth costs nothing but part of your credit limit. It really is a difference if you expect to spend money on vacation.
I love it. As someone who never carries a balance I get paid by banks for doing pretty much nothing at all.
And I don't worry about US retailers, I don't live there.
I should add that rewards are not the best benefits. Sign up bonuses are much more lucrative, running to hundreds of dollars per card, and can often be repeated. Same applies to bank accounts.
And it may not work the way you expect. Retailers may favor credit card users if they tend to spend more. There are substantial costs associated with handling cash, so cash users may end up paying more.
But of course banks make huge amounts of money from poor customers via various fees and interest payments. It warms my heart that I get some of those ill gotten gains insead of the evil banks.
It is risky and it is very easy to lose great amounts of money on a bad decision when credit is involved. Arguably that makes it bad. But still not negative sum.
Borrowers can also keep from overextending their credit and go on debit cards instead…
Obviously these things can have an impact on people but before the 80s credit cards were not widely available to people with high credit risk and the world still functioned.
I don’t have any data, but my intuition is that overall high-fee, high-reward cards increase propensity for consumer spending by at least a few % beyond the fees/rewards.
The merchants think so, too, or they wouldn’t accept the processors that let their banks hand out these cards.
Visa / Mastercard / American Express all have lines of premium credit cards (Visa Infinite, World Elite Mastercard, Amex Platinum), and they're very much too big to ban. You'd just be left with one processor in the US (Discover, now owned by Capital One).
If they’re truly too big to give up no matter the fees they charge, they’re leaving money on the table.
Of course, they can’t. If Chase started handing college students a 3% card, the merchants would riot.
In recent years, all of my utilities have added 3%+ credit card surcharges, so I pay most of my household expenses with debit cards/ACH now.
Tmobile, Comcast, Verizon, ATT, Target, grocery store, electric utility and water utility (government), annual vehicle tax (government), auto body shop, daycare, and any home repair contractors all charge 3%+ (or give a discount, same thing), so I basically only use credit cards for other retail stores and travel and restaurants.
Of course there’s going to be a a cost to spending beyond your means.
One of the most corrupting yet hidden forces in America today are the payment networks MC/Visa etc. due to their bribing and corruption of the government in order to prevent things like making payment processor fees separate/independent of the cost, i.e., similar to how taxes are added after the fact, not included in the price; and also preventing merchants from having two different prices, cash vs card.
I’m a bit surprised that HBR does not seem to even really have an accurate mental model if the matter, unless they’re making an editorial choice to speak in vernacular turns to relate it to the audience.
The problem is not really the cards, it even credit cards, it’s actually the payment processing networks that are the corrupting force.
If America has a legitimate government, there would have been a federal alternative payment processor that charges nothing as an accompaniment and based on the authority to mint the currency, which is what a payment processor today is, a digital currency mint.
To put it into perspective, when you purchase something by credit card, a merchant may have to l pay a little under 3% on a $100 purchase. When you purchase something cheaper let’s say $5, a merchant may pay 6.5%. And no, they don’t just say “awe shucks, I guess I’ll lose that money”, They increase the prices by some averaged amount.
Some may say that they can’t do that because competition, well, because there is no real competition and because the payment processor de facto monopoly/cartel has basically every single company in lockdown and you have no real alternatives, especially in places like Europe where they’ve foolishly and enthusiastically started forcing everyone into digital payment, all the merchants simply roll what is effectively a kind of organized crime/mob extortion into the prices of the goods and services the common person pays and never knows is paying.
That is not a positive. I'm fine with splitting up a price if you want to show how much tax gets added, but having to continuously do the mental math of "no this item is 10.99 it's 10.99 + tax" is very frustrating. When I pick up a $11 item, I want to spend $11.
I would even advocate that in the US we require taxation to be handled that way too because you are right, most of our citizens can't do basic math, let alone in their heads, or even really care; but if the price tag had to be the taxed price and you then get a discount if you pay cash, it would be a far better situation. There has never been a better time to do this with digital price tags.
The inherent problem is that the likes of the masses are hard to organize, let alone corral and focus on a single thing and everyone thinks they are smarter than the average.
In Europe (or at least the EEA, but the UK and I think Switzerland have their own capping) card interchange is capped at, generally, 0.3%.
