I am always amazed at how little history republicans, right wingnuts, and other assorted hate government types know. Our best years were after FDR raised taxes to over 70% and used Keynesian ideas to end the great depression. The war effort was the greatest spending spree in history and many worried that war's end would return America to the depression years. But instead America built and bought and shared and continued the high tax structure and we had our golden years of prosperity.
Reagan and Clinton raised taxes, Reagan many times.
"There is no historical evidence that tax cuts spur economic growth. The highest period of growth in U.S. history (1933-1973) also saw its highest tax rates on the rich: 70 to 91 percent. During this period, the general tax rate climbed as well, but it reached a plateau in 1969, and growth slowed down five years later. Almost all rich nations have higher general taxes than the U.S., and they are growing faster as well." Tax cuts spur economic growth
"But the record shows just the opposite. The national rate of job growth during George W. Bush’s tenure was the worst since the government starting counting in 1939....The tax changes didn’t do much for Vermont, either. Job growth so far this decade is worse than any decade since the 1940s. We have fewer jobs today than we had in 2000." Hoffman: Did tax cuts create jobs?

It is true that GDP per capita has grown at about the same rate in the US for at least 140 years no matter what level marginal tax rates have been, however it is incorrect to say that "almost all other countries" are growing faster than us. The US has been one of the fastest if not the fastest growing economy of all the developed economies in the world over the past 20, 30, 50 years. America's slow growth over the past decade is because of the collapse of asset bubbles. America has consistently demonstrated high growth in total factor productivity compared to other rich nations, which is what drives wealth creation over the long run. But this has also occurred no matter what the marginal tax rate has been in this country.
