Imagine that - an infograph gives a concise summery of a larger idea.. 🤯
Either way - it is really that simple and splitting the working class in to splinter groups is just another division, which again - only serves the owning class. Them fighting amongst themselves is irrelevant, they've been united enough to maintain this system for centuries because they have the same goal - stay in power, make as much money as possible. If that happens via collaboration one week, then they'll collaborate that week, if it means they need to go to war the next week, then they will, and have been, doing exactly that.
In contrast, as long as the working class stays divided (along race, gender, ability, and even "work level" or whatever you'd call the division you've brought up) we will never be free.
I'm the furthest thing from a class reductionist, and I think intersectionality is vital, but all of the systemic barriers we face (racism, sexism, ableism, querrphobia, and so on) exist to serve capitalism and those who benefit from it. That doesn't mean those systems don't need addressing, but part of doing that is understanding why they exist, and how they serve to divide us.
Seriously, what end could splitting hairs over "peasants" or "artisans" possibly serve (And are those hundreds of years old terms even relevant in our world with our technology?)? Even the petit bourgeois is oppressed by the owning class, the system convincing them that a "middle class" exists is part of the fucking con, and the whole fucking point is to see how irrelevant these semantics are and fucking unite so that we can have a better society for everyone.. 🤦♀️
