After WW2, most of the world's industrial base had been bombed to rubble. Germany, Japan, the UK, France gor hurt much worse than people know, Italy, Russia, the Dutch, Belgium -- almost everywhere but here.
We made a lot of money supplying the world with the tools to rebuild and start their manufacturing process again. Along with that came Tariffs applied by those economies so they could survive long wnough to become viable again. Had we not let them impose tariffs, we could have flooded their markets and destroyed their economy. Easily.
But we didn't. We let them restrict our imports and even make money off of themin the form of said tariffs.
Meanwhile, they got fat as hell. Japan and Germany got stinking rich, the UK could have too had they not gone full-stupid and went with socialism in the 50's. The French surrendered to -- Somebody. Not sure who.
We didn't do bad either, except for polluting our environment due to our over-production.
But now it's time for that to change. We carried their asses for the past 80 fucking years and it needs to change.
Now.
