From your descriptions this is just another way of repackaging lib shit. Hyper online people parroting Marxist talking points without actually understanding their implications or having actually read any of the literature to understand what these words even are or refer to, and then lib economists at think tanks writing articles based off of these hyper online screeds. Basically, describing a 'class' as anything other than a 'relationship to the means of production' is very lib shit.
