If economists think that the U.S.A. will benefit in the long run from "free" trade, why do

free trade across the board? If it's such a good idea, in general, to decimate industries and fire millions of workers, then why shouldn't Japan or Germany or Korea or China think of other people's interests. Why aren't these countries called selfish and protectionist when they think of their own best interests? How can Germany of all places still be a HUGE net exporter?

Japan loves to protect their auto industry, their farmers, their electronics industry and their precious whale slaughtering, but the USA is acting irrational if we put more than a 3% tarriff on chinese crap...

Yes, we have huge a huge and meddling presence militarily, but we don't have troops commanding anyone in those countries that we have huge trade deficits with, and don't use the oil argument, because we don't have troops in Saudi Arabia or Venezuela or Iran or Russia and that's where our oil comes from.

Most economists agree that the US will benefit in the long run from free trade. But there are many economists who support trade barriers, with the view that government needs to protect against the negative externalities that result from free trade. It's important to realize that there are many schools of economic thought and that oftentimes you can't lump economists into one group and say they all believe this. It's important to read the work of economists who have different viewpoints.
