All I can say about that if you just noticed then you were not paying attention.

Clinton signed NAFTA. This caused nearly all steel and aluminum manufacturing to move out of the country. The bulk went to Canada. Now the same business interests who want to bring that manufacturing capability back to the US are the ones who drove it out. A lot of our current troubles can be linked to how US business interests used NAFTA to weaken the american economy. Despite the orange turd being their cuck the real problem in this country are these despotic corporations and the weakening of american labor.
