Even if it was, the problem is that this is a classic trap where protecting your own market will result in overpriced goods in the home market. We would be paying extravagant amounts for everything. Most other countries wouldn’t have that problem and would result in being stuck in time like a lot of the former Soviet Union.
Then maybe it's morally right to tariff their goods? (As all countries already do, not only the US) Otherwise, what's the purpose of labor laws within the US or Europe?
