Other countries do not have the kind of business regulations and tax codes that we have here in the US. I think that plenty of companies would love to do business and stay here in the US even with our strict regulations and minimum wage, etc. However, because our government is SO greedy with its taxation policies, a lot of businesses have abandoned the United States and moved their businesses to other countries. We no longer have much of manufacturing industry left here in the US, which is pretty darn sad.
Our manufacturing output is larger than it has ever been. I don't know why people buy into the lie that we don't have much of a manufacturing industry left.
The simple fact is that we have increased efficiency tremendously. There is a concept in economics called growth accounting. On one side of the equation are "inputs" like growth in employment, increases in the education of laborers, and physical capital. On the other side of the equation are increases in the output per unit of input.
America succeeds at the latter better than any other nation on Earth. As a result, our manufacturing output has steadily increased, while the labor needs to meet that output have decreased.
So as labor demands for manufacturing decrease, it is critical to our innovative edge that we educate our laborers for the jobs of tomorrow, not the jobs of yesterday. This is where we are starting to fail.
As for tax codes and businesses moving overseas (oftentimes such moves are done only on paper), you are correct. And if we rid ourselves of the tax expenditure monkey on our back, we could easily reduce corporate tax rates.
Tax expenditures are the crack cocaine of our tax code. We need serious treatment.
