How dare you insert your evil Bushian propaganda here, you crazy Right Wing facist!
What would an economics professor and PhD know about economics?
Obviously I agree fully with you. The progressive tax code is marxist by definition. Class warfare and the whole "From each according to their ability, to each according to their need."
When it gets to the point where a majority (instead of nearly a majority) don't pay taxes, there will be no more price-value tension to keep the size of the Federal Government down because "It's Free!".
