It depends on whom you define as "middle class": I believe about 1/2 or more of the middle class touted by the MSMs are in fact elite cronies. This leaves 1/2 of the touted figures as "truly middle class". They probably live at American blue collar working class levels and yet sociologically they would be more akin to America's upper middle class in comparative scales.
Most of the population would be peasants no doubt.
I'd read stories where the peasants were treated like trash by the upper class and that the potential for class war fare wasn't out of the question.
