That summarizes Trump. He represents the group that is still smarting from the election first black President. There may be anger about their economic condition but that is secondary - you never saw a rise in racist backlash during the great depression.
Actually, during the great depression, blacks were either chased away from jobs or outright murdered so whites could have the scarce jobs. Check out how the 1933 National Recovery Act was blatantly misused. The victors always (re)write history.
Look at it just like our tribalism here in Kenya. When the economy is doing badly or we
believe it's doing badly, humans tend to group together in ethnic/tribal/clan/etc. units as a survival mechanism irrespective of how dumb and stupid the leaders who articulate their fear driven beliefs are (see Trump, Uhuru, Ruto, Raila, Mudavadi, Kalonzo et al). The Germans did the exact same thing coming from their depression (and WWI) when they went for that little mustached Austrian painter.
Trump is quite successfully tapping into that sentiment with ridiculous promises that should make any right thinking person realize he's full of it to the brim.
