Here is Dean Baker in 2009 doing this thang, which is, you know, seeing the economy more clearly than anyone else on earth:
I like Baker’s ideas about new taxes. He is not for raising the top marginal rate very much. He seems to think it could up as high as the low forties, but after that it would provide too much incentive to game the tax system. I’ve been pushing for a top marginal rate of 50%, but I think he makes a good point. I’m not sure there would be a problem with that rate, but I can certainly see a problem at 70% or 91%. (I don’t just want a higher rate; I want more high income tax brackets.)
He also wants to make the capital gains tax rate the same as the top tax rate. And he wants a financial transaction tax. I’m in favor of both those things.
