No it is not. JFK lowered the top marginal rate from 91% to 70% and revenue increased dramatically.
Taxes take away from Economic Activity. More Activity means more tax Revenue, even at lower rates.
You clearly do not understand this issue at all.
Well, if that was the case then why did the deficit start to really increase after Reagan's major tax cuts? It's not a coincidence that the national deficit has only gone up since that time.
I understand your point but people are going to pocket the extra money they make. They're not going to re-invest it. That's the problem with that theory.
