We can look at the '70's and the Keynesian approach under Nixon, Ford and Carter and see what a failure that was. Reagan, along with Volker, turned that around and outside his first two years in office so did Clinton. Then we go back to Keynesian policies under Obama and we have the weakest economic recovery since WWII.
You're simply full of it. You don't know what you're talking about. You start out with the conclusion you want ant then cherry pick and twist the facts to try to claim they support it.
Funny, why don't you list JFK and LBJ's economy under the Keynesian list? Fact is, Democrats have better growth than Republicans consistently. All Reagan and later Republican tax cuts for the rich do is lower growth, increase inequality and increase our debt.
Ya, ya, Reagan had some growth (lower than JFK and LBJ, but some).
AT THE EXPENSE OF TRIPLING THE NATIONAL DEBT. Ya, put the stimulus on a credit card you get some growth.
