Just saying, I have to wonder why shipping millions of jobs and enriching known enemies was always good for the US as far as our corporations, congress and the 1% have always advocated for lo these many years. Not so much, the US workers. Now, it is destructive, horrible and so damaging to this very economy that has been ravaged by imports and job losses because someone has mentioned some protectionism here. It was good tearing our manufacturing base apart, but not good trying to help it. Not much do I agree with tRump on, but this I must say is long overdue. Do I blame any country, no,no,no. It is our corrupt congress, our corrupt corporations and our greedy and decadent wealthy who never have enough. Power and greed and corruption will be the ruin of of us as it has for every great civilization in history. On this point, if he follows through, I support him.
This "shipping millions of jobs" subject is more complicated than you portray.
Once upon a time not so long ago, China was seen as a direct military threat as they were aligned with the Soviets and things had nearly gotten out of hand with the Russians several times. Along came Nixon's "China strategy" and we were on the path of splitting the two enemies, which was seen as all to the good. But once we began treating China as a part of the world community, another problem arose: we could not embargo them out of the world economy. We wanted them to become more like ourselves in the assumption that converting them to capitalists would make them more like us and therefore, easier to get along with. (Somewhat similar to the idea that if we gave Iraqis "freedom" they would become western style democracies).
Thus started the slippery slope. The business behavior that you perceive as greed only came later. Maybe we could have nipped this in the bud, if only we would have stopped Honda from selling all those damn motorcycles here in the 60s. That's where all this got started.
Maybe someone should start a fantasy thread about how the world would be now if we had gotten heavy on protectionism way back then.
