They are not leaving the US...?
i recently bought made in usa undergarments and the quality was better than am undergarment i bought from abroad and the price was comparable
it's not a question of "want to pay $70", we'll want to pay the lowest price possible for the equal goods. if the cost of shirts doubled, you might buy less of them and wear them longer. i remember my dad probably had 5 nice dress shirts, two suits and a sport coat.
i'd rather have $70 (or $100) shirts and a functioning middle class.
Today, we have pretty low unemployment so jobs isn’t as big a concern as other times. BUT jobs are not evenly distributed across the nation. If you visit the rust belt, those cities and towns are losing population as they lose jobs. That makes for an angsty population - staying in your hometown means fighting over the shrinking job pool. No one really wants to be a coal-miner or factory worker, but when that was the last big employer in your shrinking town, you get nostalgic for “good days” of high employment numbers, and a growing population.
Garments aren’t coming back unless American shopping habits change. We’ve started spending a smaller % of income on clothes, while buying more units of clothing per year. That favors clothes made by fast fashion under terrible work conditions - which will never be local. Unless you want to buy a $200 pair of ethically made jeans, you’re not getting it American.
