What government policies are you referring to? Businesses moved manufacturing to China because their goal is to make as much money as possible. The only potential barrier is if US citizens would care that it wasn't made in America. Products are labeled and most people don't care.

This is an American quality where a person who works in a factory that makes extension cords and needs their job to survive would buy the cheaper lamp even though it's made in China.

Most people aren't willing to make financial sacrifices to help people they don't know EVEN if they might be affected by another person having the same belief.
