Marxism has a term of art for “middle class”: bourgeois.
Marx on the middle class: “Society can no longer live under this bourgeoisie; in other words, its existence is no longer compatible with society.” (Communist Manifesto)
Lenin on the middle class: “We fully regard civil wars, i.e., wars waged by the oppressed class against the oppressing class, slaves against slave-owners, serfs against land-owners, and wage-workers against the bourgeoisie, as legitimate, progressive and necessary.”
The middle class is anathema to all sorts of socialism, but most especially Marxism, which is all about class struggle.
The utter ignorance of Bernie supporters of this essential fact is astounding.
Sanders supporters are bourgeois.
They’re at hippie music festivals, vegan restaurants, prestigious colleges and universities, wearing tee shirts, they’re all over Twitter, Hell - they even have Wiccans doing rituals for him.
The greatest irony is that the Marxists have made their philosophy cool with the middle class.
It’s amazing to watch.
