If there’s a cap on the price of a type of good, then obviously only the lowest quality things get made. If you cap shoes to $10, they will only sell shoes imported from sweatshops.
If you specify exactly how something is made, like $20 for made in USA shoes, they will import it from a sweatshop and sew a logo on it in the US.
If you specify how much labor must be done in the US, there’s a chance nobody would bother since selling the $10 sweatshop shoe has better profit margins
