No, that's why I said capital gains should be subject to a progressive tax system.
That is how every other income tax (other than FICA taxes which are regressive and capped at a certain amount of income which is also ridiculous) works.
For a single filer, income between $0 – $8,700 is taxed at 10%. Income between $8,701 – $35,350 is taxed at 15%. Income between $35,351 – $85,650 is taxed at 25%. Income between $85,651 – $178,650 is taxed at 28%. Income between $178,651 – $388,350 is taxed at 33%. Income $388,351+ is taxed at 35%. Income from capital gains should be treated the same way. It was largely done this way until Clinton lowered the rate to 20% in 97, and then George Bush capped the tax on realized capital gains at 15% in 2003.
Currently, income from long term capital gains is taxed at 15% across the board, unless you are in the 10% or 15% income tax bracket in which case you pay 0% on capital gains. Romney and Ryan's plan does away with capital gains taxes, taxes on interest and dividends completely.
