Tell me, just exactly what "value" do financial intermediaries add to GDP? About $1.44 trillion in Q2. Now, to the claim that I have not explained why a 50% corporate tax rate results in more investment than a 20% rate. I have explained it profusely. And your explanation was something like, "A company wants a return of its capital more than a return on its capital, so they'll invest more at a 50% tax rate because if they fail, they'll have a bigger write off" Is that about it? try the Angry Bear, you know, a group of financial professionals, most with Phd's in Economics. Thanks for the link. Looks like they're discussing more of a Laffer like curve idea, not that, in the original claim, a 90% rate yields more investment than a 20% rate.
