The question to ask is why capital gains tax should be lower than taxes on wages? If encouraging work is the priority, it should be the other way round.

1. Earned income 2. Investment income 3. Gambling/lottery/short term income
Tax rate should increase as you go down that list.
At a 6% return, you need around $800k+ to get the equivalent of a $50k salary before taxes from the interest earned on your savings. When you factor in having to reinvest some of your returns to beat inflation and make up for some years of low or negative returns, you might only draw maybe $20-25k out of that $800k portfolio. Then you get taxed on it at 20% capital gains along with any state taxes, and it all adds up to a lot less money to live off of.
Most people who want higher capital gains do not have a portfolio of this size nor have they explored the reality of living off a portfolio of this size. Work to the grave I guess.
As a thought experiment imagine if everyone did this, or it was everyones goal.
You realize that 50k salary is rather close to the median individual income in the US, right? Why should the fact that you've got 800k making money for you mean that you should be taxed less than someone that earned their 50k through wages and tips?
Edit: Another way to think about it: Both the investor and the wage earner added value to their respective markets which was valued by their markets at 50k over the year. Why should one of these market actors be taxed lower than the other?
my prevailing theory is the common belief that an investor's money brings in more economic knock-on effects, and the $50k earned by the wage earner is less "powerful". in order to incentivise the investor, they are given a tax break.
this isn't helped by the fact that those in position to make this sort of tax law are also beneficiaries of said law.
the lower rate of taxation incentivizes one to invest that money in legit investments, rather than spend it on discretionary consumption or invest it in an illicit vehicle that provides an untaxed return.
> Why should one of these market actors be taxed lower than the other?
I personally don't think they should but another way of looking at it is that people usually have to work (the enormous pile of cash came from someone somewhere, even if it wasn't the person who has it now). so theres no incentive for the government to cut the worker a tax break. but when you have money in the bank you can do many things with it. a lower capital gains tax allows the government to earn some revenue on the money and helps keep that person from spending it all on fun stuff and driving up the cost of resources with 800k worth of bids.
If you are talking about non-retirement people, I don't expecting to live your entire life off of 800k in savings is realistic or something we should encourage. We need people working and producing things.
Though, it should really be a tiered system in that case - different tax rates for holding periods of <1 yr, 1-2 yr, 2-3 and so on, instead of just <1 yr & >1yr
For practical reasons the state does not demand the tax until the accumulated gains have been realized by selling the asset. This makes sense for illiquid assets like stock in your private startup, but I don't think it should change the calculation of when the tax was incurred and how much. For liquid assets like shares in public companies, I think it would actually be perfectly reasonable to demand the tax on unrealized gains.
But if you buy a stock for $1 and it goes to $2 as a result of inflation, you get taxed $0.5 on the $1 gain, but your resulting $1.5 has less purchasing power than the $1 you invested.
I think the way to mitigate this problem is to index capital gains to the CPI and then tax gains like income. This cleans up the tax code quite a bit, stops favoring capital over labor, and balances out the pressure on the CPI with having a powerful group of people wanting to have it go up. At the moment CPI is probably under-reported and keeping social security and other inflation adjusted things lower than they would be otherwise.
The market can easily adjust prices for assets to factor in the cost of inflation and taxes.
