I grew up in a “rustbelt” state, and was told my whole life how Americans are too stupid any lazy as compared to asian and mexican workers, while teaching those same people, and building machinery to send to their countries. At the same time, I was told that I make too much money for providing those services to my employer, while I watched my employers making record profits, while claiming poverty, and shedding US employees like a biblical plague.
That same scenario has played itself out in Wisconsin, and that lesson isn't lost on the people there.
Walker is from there; he's probably witnessed it first-hand.
Wisconsin has (had) a lot of heavy industry, just like the rustbelt state that I came from. It's good to here that a candidate is willing to put the interests of Americans first.
