Super post! I don't think they will ever get. It has something to do with manufacturing their own reality and then the facts don't matter. Reminds me of my first wife.
It is obvious that this guy has not done any economic modeling! Money does not get taxed once as it passes through the economy. It gets taxed each time it changes hands. As I recall money spent by the government changes hands something around four times and private industry money changes hands six to eight times. This explains why government spending does not spur the economy as much as private spending. It also explains why tax cuts that spur the economy increase government revenue. This can be seen now in the increases that we see in federal revenue after the Bush tax cuts.
