Contrary to popular opinion, many foreign companies want to open businesses inside the US. Here is a story about one such firm:
In a former life, I wrote air pollution permits for a state environmental agency. We frequently got applications from foreign firms wanting to open facilities in our state: from China, Germany, Italy, Korea - you name it, they wanted to come here.
It was US companies who were fleeing the US in search of higher profits, cheaper workers, and decreased regulatory requirements.
So, from my perspective the real problems with our economy were not caused by foreigners. They were manufactured right here in the good old U S of A. And we're STILL not holding the bums accountable.
