I've seen people complaining that the article is disingenuous because it conflates income taxes with capital gains taxes. My response is 'so what'. When you make above a certain income level, you don't need anymore income and can play around with reinvesting capital gains to push taxes into the future while amassing wealth. Sure, you're not realizing the income, but what you're doing, I think, is gaining power and influence. To me, it makes some sense to tax capital gains the same as income, at least above a certain amount.
