Ok, so here is the challenge. I have proof through US tax collection and economic growth of the Kennedy, Reagan, Clinton, and mid-GW Bush years that lower taxes and decreased government spending increases both government revenue and the size of the economy.
I want to see proof from the other side. Proof that raising taxes on businesses, increasing "fairness" in regards to income, and massively increasing government spending actually helps the economy. I can look at the various recessions around the world, and The Great Depression in the US to prove that it doesn't, but I want to see where the heck people are getting the idea that it does. Nobody has yet given me anything but words.
