China isn't a friend of the USA, nor is it our enemy (yet). They are just trying to do business the way we do if we had the advantage. Their goal? -Reap as much profit, wealth, economic growth & development and keep their own people happy. The problems of our economy are not their problem.
It is no longer possible to live in an isolationist world, if you think it possible, then the first thing anyone should do is to throw away their computer, and probably all of your electronic gadgets including TVs, phones, cellulars, MP3/iPods, etc. since they are ALL made in China nowadays. Unfortunate but true.
Lastly, for every $1 you spend on a "Made in China" product, only about 1/3 of that amount is kept in China - the remaining 2/3 goes to the shippers, transporters, distributors, middlemen & retailers -which are all American. Funny how lots of people in the USA have jobs because they support China imports.
