Democrats like to call Republicans "the stupid party" often because conservative politicians refuse to accept controverted propositions - the efficacy of Keynesian economics, the existential nature of global warming - that Democrats want to regard as "settled." Sometimes, however, conservative politicians do make claims that are not true as all human beings tend to do.
But President Obama is making policy based on assertions of a fact - the rich pay less in income taxes than ordinary Americans - that does not bear the slightest scrutiny. It is simply not true.
Perhaps our tax system is not progressive enough. Try to make that case, but at least get the data right.
Of course, it is true that capital gains rates are taxed at a lower rate than ordinary income - this is the source of the tax break for those dread "hedge fund managers" - all 193 of them. There is economic theory justifying differential treatment of capital gains. I tend not to buy it. I think that all income should be taxed when it is realized and at the same rate regardless of source. But even under my view you have to adjust the basis so that only "real" gain is taxed. But the idea that our tax system "favors" wealthy people is not rooted in reality.
Having established that, the proposal to raise taxes on higher income earners in order to avoid reductuins in entitlements reduces to the argument that they can "afford" to give the rest of us some money. Why isn't that class warfare? It is nothing more than the assertion that some people have more than they need and rather than appeal to their charitable impulses, the "excess" should be taken from them by legal compulsion which, of course, ultimately reduces to threat of force.
The moral superiority of this position - supposedly reflected in Wolf Blitzer's "gotcha" question to Ron Paul - is not self evident. Christians certainly are charged with concern for the poor but one cannot discharge that moral obligation with other people's money.
Having said that, unlike Paul, I am not a libertarian and I think that, if for pragmatic reasons alone, a social safety net supported by moderately progressive taxation is appropriate. But no one really disputes that.
