Obama said last year that itemized deductions for the wealthy should be phased out — then on his own tax return, claimed a huge itemized deduction. Until those who advocate higher taxes for the well-off practice what they preach, the national debt situation may only get worse.
This is one of the most annoying tropes in existence, on both the left and the right. The point of laws is to provide a level playing field, and no one is a hypocrite for following existing law even if they think it should be changed. That goes for congressmen who accept earmarks even though they think earmarks should be banned, it goes for drivers who park for free on city streets even though they think parking meters should be installed, and it goes for rich people who pay taxes at the current rate even though they think that rate is too low.
No one is obligated to be a sucker. The whole point of taxation is that it's a collective enterprise: I'm willing to pay my taxes for the common good as long as everyone else is doing it too. But until then, there's no reason that I should impoverish myself (or my constituents) while everyone else is merrily taking full advantage of current law. Fairness matters, and that ain't fair.
