The term bourgeois originated in medieval France, where it denoted an inhabitant of a walled town. Its overtones became important in the 18th century, when the middle class of professionals, manufacturers, and their literary and political allies began to demand an influence in politics consistent with their economic status. Marx was one of many thinkers who treated the French Revolution as a revolution of the bourgeois.
It makes a lot of sense and is applicable today. Many of the people consistently hurt are poor uneducated rural individuals. Who've been conditioned to hate the educated and vulnerable minorities. Most of the people calling for specific change and revolution. Are disproportionately college educated, and typically at least from families that were better off financially.
If you're constantly having to work and struggle just to not fall further down. You don't have a lot of time to look around or even think about anything else. That's part of what's kept people so trapped in the system. Just trying to keep up and not fall out of it. It's why they try to keep unemployment low but under employment high. And make all the welfare programs they cannot abolish as much work as possible to use. Unemployed starving people turn violent very fast and rightfully so. They are starting to rapid fire into their feet at this moment though. Planning on AI replacing everyone. They are also banking on having robot bodyguards sooner rather than later that won't turn on them. But I don't think even that will save them.
