The reality is, anyone who knows anything about economics knows that taxes inhibit economic growth.
The idea that this is wrong, is so absurd that it should be laughed at.... only the problem is, most americans are absolutely ignorant of economics and thus can be tricked into believing it. Or in your case, assuming that "the vast majority of economists" think this, and have done so "for decades".
Frankly, it is astounding how much you have rejected economic as a science while thinking the partisan ideology you're pitching is "economics".
