If and when we have more manufacturing in the USA, prices will be higher. Higher for the US made stuff and higher for the imported stuff (because of import duties). Everything will cost a little more maybe - at least for a while.
If you are not old enough you might not remember how things worked before "Free Trade". It was not perfect and it kind of sucked actually, but at least we had a middle class! These days after 20 years of globalization you have a different society. Maybe it would be different for other reasons too, but I do see what I believe to be some effects of NAFTA globalization. Some good, Some bad. Some bad here, some good "there" and vice versa. You decide.
