"The Obama Rule"

I'm working, sort of, on some commentary related to the proposed "Buffet Rule" which will raise taxes in the name of "fairness," but until (and unless) I finish, here's some good (and relevant) stuff from the Wall Street Journal...

The century-long history of the federal income tax teaches us one lesson over and over: The higher the tax rates, the more loopholes Congress inserts as a way around those rates. This is why the government collected roughly as much tax revenue as a share of GDP when the top tax rate was 70% in the 1970s as it did when the rate fell to 28% in 1986.

The Buffett rule is really nothing more than a sneaky way for Mr. Obama to justify doubling the capital gains and dividend tax rate to 30% from 15% today. That's the real spread-the-wealth target. The problem is that this is a tax on capital that is needed for firms to grow and hire more workers. Mr. Obama says he wants an investment-led recovery, not one led by consumption, but how will investment be spurred by doubling the tax on it?
