To make one more point on this argument that conservatives want tax cuts because they think the rich give all their money to charity, if this were actually a big part of anti-tax attitudes, then conservatives wouldn't be advocating the end of the estate tax, which supercharges charitable giving among the wealthy (the government can't confiscate what you've already given away). Repeal it, and you sacrifice about $10 billion in philanthropic bequests and contributions yearly. Conservatives -- and libertarians -- don't seem very worried about that, but then, I don't think they're signing anti-tax pledges to make a triple bank shot for charity.
