Most of those jobs don't exist here anymore. Over half of all imports from China are consumer electronics, furniture, clothing, toys, and plastic goods. Those industries are all but extinct in the U.S. and have been for some time.
To reinforce your point, I’d suggest that the strongest protectionists in the U.S. would rather die than have their own children work in a factory that produces consumer electronics, furniture, clothing, toys, etc. I’ll offer Donald Trump as the best evidence of this.
Slap a tariff on them even if it causes an increase it retail, most of the tariff will be eaten by the importer. It will not take a large tariff to equalize the cost competition between the third world and the USA. 10% at most. It will raise revenue and help pay for the social costs of high unemployment. It will dissuade future decisions of gloBULL corps. It will incentivize countries like China to re think their trade war on us.
Those extinct manufacturing can come back at the drop of a hat.
