Here's a decent article regarding this topic
Economist Mike Walden
The article opens up by saying:
"The dollar is falling against foreign currencies. Our trade deficit has swollen to record levels. Foreign investors have bought large quantities of
our government debt. With all these financial facts, it's easy to get the idea that foreign interests are getting the best of our economy. In fact,
some argue foreign countries now effectively control our economy. Let's see if this is a real concern or misplaced anxiety."
Just thought it may be relevent.
