I'm throwing out too many ideas at one time. I'll stick to the topic of how rich people should be taxed. I'll save the 401k and IRA talk for laterUltimately, money withdrawn from 401K's & IRA's is taxed at regular rates, other than Roth IRA's. It just grows tax free, as does money invested in hedge funds & private equity firms.
About the bolded part, sort of yes and sort of no. It depends what kind of growth it is. Stock price going up is tax free because that's theoretical gains; it doesn't translate into real dollars until it is sold. When sold, you pay tax on the gains. Interest on bonds is taxed. You buy bonds, it pays interest, you get taxed on the interest even if you didn't sell the bond. Dividends are taxed as well. Even if the money goes back into buying more shares (Dividend Re-Investment Program), you're still supposed to pay taxes on the cash value of the dividend. Of course a lot of people don't since it's harder for the government to track things like that...
Forget 401K and forget IRA. Let's talk about the money that rich people deal with. You own a large number of shares in a business (such as owning the entire company) and its profits are considered capital gains. How should this be taxed? Let's take some numbers out of the air to show what I'm thinking. Let's say the business grosses $1,000,000 per year and the costs are $800,000 per year. Operating costs are tax deducted like normal and we're left with $200,000 of capital gains. Maybe the first 100k of that would be tax free; a reward for your doing a good job of being a Job Creator. Let's say the rate of regular income tax is 30% for all money over $80,000 for someone with a regular job. If you had a normal salary job and you made $200,000, you would be taxed at 30% for $120,000 of that income, and the first $80,000 would be taxed at a lower rate; you pay tax on the whole thing (not including deductions).
Because you're a super awesome Jerb Creator with a successful business, that 30% tax rate would kick in at 100k instead of 80k, and none of the first 100k would be taxed. That sounds like a pretty sweet deal, right? If you start your own plumbing company, you could make quite a bit of money before the tax man comes after you. If you were a super rich bastard like John Kerry or Mitt Romney, my suggested plan would actually be a HUGE tax hike. They don't pay anywhere near 30% at this time.
