America often outsources the production of its products to factories in countries like China, Korea, and other Asian nations. Once these items are produced, they are shipped to the U.S. for assembly.
In contrast, if a product is made entirely in the U.S., it goes through various payment processes, including healthcare insurance, other insurances, taxes, and additional expenses, before being assembled and shipped out.
I'm sure you've heard about how the U.S. sometimes hires foreign workers who work long hours but are paid very little because they, whatever company/companies, are cheaper than a US citizen
At other times workers make a "Union" that makes the companies obligated to follow their demands in exchange for fair work otherwise lawsuits
