People who aren’t paying rent after the pandemic started likely aren’t doing it for fun. Most likely they are underemployed, hence collections will stack up. “Living within your means” assumes it is even possible to find employment and a handful of life/medical/mental/family stability that not everyone has.
You seem to underestimate how much of modern life in the USA depends on credit. Electric, water, telephone, internet service require credit or suffer the costs and inconveniences of prepayment. Rental housing almost always requires credit checks in any desirable market.
You also seem to assume that collections can never be converted into a lean on your assets or garnishment of your wages. And that doesn’t even begin to crack the strange and painful tactics debt collectors use on your family, employment, friends, and other social pressures.
> This is all a result of me living responsibly within my means.
Implying that not using credit cards is how one lives responsibly within their means is kinda weird and wrong. Yes, you can live irresponsibly with a credit card. You can also live responsibly with it too. And it will give you extra consumer purchase protection (in case of a fraud or a bad fair vendor), as well as 1-5% return on purchases.
Some would argue that missing out on that 1-5% return and extra consumer protections is the irresponsible move. But either way, the whole "using credit cards means living irresponsibly and outside of their means" is absolutely nothing but a complete lack of understanding of how credit works.
The preceeding is a statement about most of my life. I've gotten better at such stuff and my lifestyle has changed after grad school -- and since I didn't have credit cards while living below the poverty line and generally being a schlub, I didn't fuck up my credit, so a few months of having a credit card as a de facto adult earned me a near-perfect credit score when I needed it.
Functionally, a credit card would work exactly like your debit card or cash, except you would also be reaping all the benefits of credit cards and improved credit scores.
But overall, I agree with your point about cost-benefit analysis and impulse control being difficult to overcome.
> I often wonder how people on the verge of eviction think about this kind of thing — whether it is salient or even understandable
My answer is that people in those situations think about these things very differently than people who have never encountered them. Or, flip it -- if dings on your credit score are the worst speedbump that society has thrown in your path, you probably don't have the skills necessary to live broke.
I didn't come for financial advice, but thanks
