If it is so good in China, why do they want to come to the U.S.?

That's a fairly easy question to answer: Because we have more to loot here and a president who will assist them.

Also,According to an old German saying,”A smart fox doesn’t eat his chickens too close to home.”
Chinese understand that they can do things here that would get them shot back in China.
