whatever tax revenues went into that effort would, if left in the hands of the people who earned them, have been available for investment that would have brought economic growth in other fields. That might well have created more jobs than this experiment in totalitarianism is claimed to have saved.
This rationale needs an injection of reality. The investors in this country have hardly ever been taxed at a lower rate than they are now. They are flush with cash (Quantitative Easing + low tax rates) that is curiously not creating jobs at the higher rate you speculate. That is because demand creates jobs, not cashed up supply.
