Because the Chinese also makes capitalism work here is well ;)
Don't kid yourself, not every American whose family have been here for generations contribute to the technology and entrepeneurial spirit of America. There are large swaths of American living in trailer parks whose offsprings are addicted to meth (yet, you guys like to talk about the crack houses in the inner cities).
There are new kids on the block in places like Silicon Valley. Unfortunately, the folks out in the trailer parks seem to take all the credit for America's continued progress and blame others for any shortcomings.
You are clearly a racist in attitude.
