The public seems to think so. That's what the polling data says, even a majority of people making six-figure incomes say that the top marginal rates should be higher. It's been the public consensus for years, and that consensus was reflected in US tax policy, too, for the most part. The best PR that money can buy, however, has had some success at chipping away at both public perception and government policy. Actually, that's an understatement. It has essentially purchased one political party, and at least rented the other.
I agree that the government spends unwisely—the Iraq War being the best recent example, or Bush's Medicare Part D plan, or some of the truly rotten things Obama did to get the insurance companies and the AMA on board with the ACA. But, yes, I think we absolutely should tax the rich more. I think we ought to have real family leave; I want better access to affordable higher ed. I want more and better subsidized housing. I want single-payer HC. You know what, though? I'm a capitalist. Shoot, I run a small business. But these are things that I think make for a better society, and they are things that a Club For Growth tax regime is just not going to deliver. So, given the choice between doing this on the backs of the upwardly-striving middle class or the investor class, I know which I'd prefer.
Warren Buffett was absolutely right when he said that class warfare exists, and that his class has won.
Sturg, quit trying to make me feel sorry for the super-wealthy. Quit demonizing the poor, the unemployed, or senior citizens. Show me how giving even more favorable tax accommodations to the very rich will lead to meaningful economic growth and widespread prosperity.
