History Lesson: his rich "friends" are who demolished american industry by moving to China where lower overhead & child labor was fine. So his rallying cry towards the offspring of those who were defeated & devastated when the US companies moved to China...was him bitching against all he & his cronies did & do.
& now... all those companies... have to pay a 75% on their shit they cheaply manufacture abroad & flood the market with here. In order to keep doing so. Because he was trying to show the world that old white man Bullying still works.
Trump is at war with the United states. Plain & Simple.
Hitler destroyed the German govt in 53 days. So he's got numbers to try& make.
