The irritating thing about Buffett is he wants to change the system that he exploited to get super rich. It reeks of pulling the ladder up after him.
There are rational arguments to be made on tax policy, but saying you pay less than your secretary is not one of them. If he objects to the carried interest dodge that he apparently uses to maximum effect, then he should say so, instead of implying that there is some huge conspiracy against wage earners.
It's disappointing that someone like Buffett can't make a better argument than the crude demagoguery Obama spews. The fact is that higher earners pay a vastly disproportionate share of federal taxes. No doubt there are loopholes, like carried interest, that should be addressed, but the slur frequently voiced by Obama that the "rich" do no tpay their "fair" share is absurd. Nearly half, mostly obama voters, pay nothing at all. Are they paying their "fair" share, particularly when they are the ones getting benefits?
