I'm more specifically talking about the effects of tax cuts and their way of stimulating economic growth.Bush and MOST GOP understand it. Reagan understood it. It seems the last Democrat that understood it was John F. Kennedy.
It doesn't take a rocket scientist to see the after-effects during the 60's, 80's - 90's, and the current rebound to figure it out.
Demokrauts think that raising taxes is good for the economy.
You cannot PROVE that tax cuts stimulate economic growth, and more than that you can't prove that they create employment. there's a little thing called the human factor that is usually left out of orthodox economics.
