Positive social and environmental effects on outsourcing manufacturing to China?

Here is one from the conservative tink tank Heritage foundation listing benefits to US.

when you outsource to places like china then the cost of the product (for you to buy it here in America) is less because their economy is less with regard to currency. Because America's economy is higher it is difficult for Americans to buy American products because the cost is so high. So in the long run 2 countries combined, working together, can supply work to their people and we can buy less expensively, and both countries then flourish.
