Perhaps because they, unlike you, are familiar with basic economics...?
Basic economics.
Such as, two generations ago America had the largest, most magnificent and innovative manufacturing base in the history of earth.
We led the world in science. Technology. Manufacturing. Inventions. Education. Standard of living. Just about by every measure we were the best.
What has “free trade” brought us?
We have lost our lead in science. Our technology is made in China. Our manufacturing base has been destroyed.
We only invent things to outsource them, immediately.
Our education system s_cks.
We’re broke. Our unemployment rate is soaring, and we are forgetting how to make things.
THAT basic economics???... :-/
