U.S. corporate tax rates may be among the highest in nominal rates, but look at what corporations actually pay. Far far lower. Corporations used to be the source of about 30% of the US tax revenues. Now it is down to about 10%. More to the point, the cost of moving US jobs overseas is tax deductible (Republicans have blocked legislation reversing this) and foreign profits are tax free if held overseas. As for manufacturing, Germany is more socialistic and has higher tax rates than the US, but they have expanded manufacturing. How? Go look.
