the wealthy will make money no matter what. its the little investor that gets hammered.
going after the wealthy is impossible, and saying that it is a goal is ultimately dishonest. there has never been a piece of tax legislation written that didn't have loopholes written into it (many of them for specific individuals) that you could drive a truck through. the wealthy have the means to take maximum advantage of those loopholes.
raising taxes on those making over $(fill in the blank) harm small businesses. ah, but The BarackStar! will give you a tax credit for this, and an SBA loan for that, and a government incentive for something else, and a rebate for yet another thing . . . hey, wouldn't it be easier, cheaper, fairer, and much less insane to just not confiscate their income in the first place?
