Ah yes, I agree with the point. Maybe "middle class" is not a very helpful conceptualization after all. Especially now with neoliberalism rebooting capitalism to its default mode (after the anomalous 1950-1970) and society finds itself in early 1900s in terms of inequality. This will I suppose be even more the case in covid times with so much of the middle class being indebted and forced into precarious jobs.
