Fair point. Outsourcing was not the right word to use, China today makes products over all quality ranges and almost always they are cheaper than any other alternative. “Giving away” would be a better word.
We leave a large part of the question of where things should be manufactured to the market. If the market decides that the place is China it's probably because they think it's individually beneficial to them, not an act of charity.
The point is that we aren't "giving away" manufacturing to China. We've already given the choice of where to manufacture to the free market, which then turns a profit by buying their manufacturing services from China. I don't see a good reason to construe it as anything else.
