Congratulations Trumpers, you played yourself.
Sorry kids, but if you can't compete with other countries fairly, you don't deserve to stay in business. There's no faking it in economics. If you try to fake it by protecting bad unprofitable industries, you end up like Venezuela.
The goal of economics should always be efficiency. If that means letting a Chinese person do something because they can do the same thing for cheaper, LET THEM. Americans will find something else to do that takes advantage of their skills.
If you think a person in China is your competition, then you have already lost.
Wow! Where to start. Do you really not have a clue as to the importance of domestic production of basic commodities like steel and aluminum? Let’s take your scenario to its logical conclusion. Because foreign companies like China can produce steel cheaper American steel companies cease to exit. Now comes a global political crisis, like say China invades Taiwan. To keep us from interfering China threatens to stop steel shipments to the U.S. China is also a major source of rare earth metals that are used in technology like jet engines, smartphones, rockets, etc. China is not our ally.
