Just calling out that worker protections and increased labor costs seem to be the result of workers making more money. As the work force becomes wealthier, they _need_ less money, and their standards rise. This means their labor becomes more expensive and they demand safer workplaces. They demand more time off. This happened in the USA and is currently happening in China and other low-labor-cost nations.
I think the person you responded to is right. The USA can and should restore its manufacturing base, for many reasons. The whole country would greatly benefit from the return of blue-collar jobs.
I don't have sources for this, but the info is out there.
Also, there are a lot of nuances around this topic that I'm not getting into here. Just want to acknowledge that...
