This article is a good introduction to the supply side/laffer curve arguments. I'll find some more links and post them. These theories are not vague handwaving. Arthur Laffer, and others in the Chicago School of economists (Friedman, Hayek, etc) have studied and published on these matters. And unlike Keynesian economic theory which was proved incorrect by the stagflation of the 70s, it has been an accurate predictor (on the large scale).
