:-) the middle class is the subset of the working class that has no food insecurity but has a lot of social & image insecurity

But like the rest of the working class, the middle class is one or two tragedies away from becoming homeless and marginalized, despite the lack of awareness regarding so

There never has been. You either sell your body and labour, or own enough capital for it to self sustain, or at least be sustained by the labour class.

Of course there is no middle class!
