Naaah. The post-war revival in the economy was largely a result of having dismantled the FDR New Deal and its attendant control economy. No, not the Social Security part or anything like that - the part where politicians and regulators thought competition was bad for consumers, and spent the decade propping up their preferred cronies with price controls and selective bailouts and other such nonsense. With the politicians, of course, receiving ample campaign contributions in return. Taxes still damage the economy, it just turns out there are things that can damage an economy more than taxes. :)

Ah, the New Deal, when our leaders thought they could lead us out of famine and into prosperity by burning crops. Birthplace of big-agribusiness! Et cetera.

Turns out, when you redistribute wealth under specific historical circumstances that no longer prevail, consumption increases so rapidly that the economy takes off.

I disagree with you in part, but would rather not debate it online.
