I spent a long time going through European histories as a prelude to going through the works of Marx and Engels. The Communist Manifesto is a shorter rant from 1847 that I vaguely remember some reading of when I was young. It is good to go through it again. The observations of social upheaval associated with the industrial revolution are noteworthy, although it would hardly need a communist to observe the obvious. As I am writing this, I have also started "Revolution and Counter-Revolution, or: Germany in 1848", by Engels and Marx. The social changes were causing upheaval in social structures and politics, with the main change being the old aristocracy being superseded by a Bourgeoisie (i.e. a prosperous middle class). The give and take associated with this messy process was certainly great fodder for rabble rousers. Marx seems to think that the trend would eventually lead to some international brotherhood of oppressed workers who were mutually sympathetic and supportive.
One thing that sticks out is the fact that the communists wanted to abolish the family on the grounds that it was invented by Bourgeois capitalists for the purpose of exploiting women. Fast forwarding to our own day, much of America - particularly the black underclass - lives in a family-less dystopia that is the inevitable consequence of such behavior. Meanwhile, intellectuals continue enraged at the institution and desperately pushing for change which is quite literally "for the hell of it". But back to women. In the process of identifying class and class struggle, it seems that the class of women is one more to be indoctrinated with exploitation theology.
Universal, government supplied education is proposed in here, which is hardly novel. I am wondering how Marx would view our current age where class struggle and exploitation indoctrination is spoon fed to the indigent classes through the Bourgeois designed, government schools.
So what remains? We can always divide people up into categories based on different features, then compare their relative prosperity. If the contrast of situation is great enough, we can then exploit these differences for the purpose of stirring envy and riots - and - if we happen to be a well positioned Bourgeoisie, we can profit from the chaos. But Marx and Engels noted this as well, as they observed that the clever wealthy classes quickly jumped onto the socialist bandwagon.
