It’s weird that the white working class gets blamed for every ill, but voting turnout from the working class is very low, comparatively. And because of the general lack of wealth they of course have very little (almost no) political influence.
It was not white working class voters who were responsible for Trump, though they to be fair did vote for him in high numbers. Instead, what caused Trump was a long destruction of all of society by neoliberals and laissez-faire worshippers, all enabled by Third Way Democrats like Clinton and Obama.
But dopey little centrists want to blame the white working class for everything as a convenient scapegoat for their own massive failures.
