The idea that we’ve “abandoned” the working class is based on a) assuming the working class is all-white, and b) that the WWC voters who shifted to Trump did so because for economic reasons. Both these assumptions are false. And when you accept that POC are not only members of the working class, but disproportionately so, that whole argument falls apart.
Why are Democratic POC leading Fight For 15? Why did POC vote overwhelmingly for Clinton? Why did Black towns in the “Rust Belt” stay Dem when their neighboring white towns didn’t? Why did rural reservations stay Dem? The rural Latino South West? The Black Belt? Why did Asian Americans, the people most adversely affected by the housing crisis reject Trump and vote overwhelmingly for the Dems?
