That isn't what I'm saying at all, and different economic theories don't change history. I'm saying there has never been a clear example of trickle down theory working the way it was sold to the public in the USA. A tax cut to the top tax bracket(s) has never on it's own generated more economic growth than the value of the reprieve. It is a flat out lie what some of the people trying to sell this tax bill are saying, including but not limited to "it will pay for itself." It will spur growth, sure, but it will also add to the deficit because it isn't going to grow the economy more than $1.5 trillion.
