Obama got re-elected by the working class, after apparently four years of alleged "down-talking". In 2012 (his closest victory) he handily won the <50k income demographic. He handily won union households (58% to 40%). He lost college graduates, but won high school grads, and HS and college dropouts.
It seems to me that a lot of the "working class" weren't seeing what you think you were seeing.
