Tax havens?

Some of you posters seem like scary people. I’ll just leave it at that.
Today’s topic has to do with President Obama’s announcement that he wants to make it harder for U.S. companies to invest overseas to avoid taxes in this country.
So I ask, what is a tax haven? Isn’t it just a place that offers advantages, or a more competitive tax rate than does the United States? Look at it this way: When Utah offers a business tax incentives to relocate here, doesn’t that make this state a type of tax haven in comparison to other states?
I suggest you read this essay titled, “In defense of tax havens,” by Richard W. Rahn. As he says, these havens “are for the most part no more than way-stations to temporarily collect savings from around the world until they are invested in productive projects, such as building a new shopping center or semi-conductor plant in the U.S. This enables a better allocation of world capital, leading to higher, not lower, global growth rates.”
Regardless of U.S. tax laws, we remain in a global economy. Most industrialized nations do not tax the foreign earnings of their companies. That means Obama’s plan would put U.S. companies at a disadvantage.
How is this supposed to get the economy moving again?
