I agree that they’re not playing completely fair, but nobody plays completely fair. They protect their manufacturers like we protect our farmers. The fact remains, it’s cheaper to manufacture most things in China than in the US, so even if we manufactured more goods here, we wouldn’t be very competitive over there.
Besides, that country is so big, who cares if we have to manufacture goods there? How many billions did Apple alone make selling to the Chinese market? And how many millionaires were created in the US as a result? The same goes for Nike, GM, Starbucks, FedEx, Microsoft, etc. and a healthy chunk of that money comes back to the US in the form of taxes.
Lastly, what does it matter that they’re communists? America is far from perfect and we should not be so arrogant to believe that our way is the only way or the best way. In fact, some would argue that the fact that we don’t provide universal healthcare is a major humanitarian issue.
