The Two Main Ones

The Bourgeoisie: AKA: The Owner/Capitalist Class, The Owners/Capitalists or “The Minority”. The owner class is the class under a capitalist society where they own the shit that operates the “means of production” (examples would be: owners of big and well-known places, like a supermarket or fast-food chain, all across a nation or more and CEOs). They relate to the “means of production” as basically the machine’s owner (duh). They’re always the minority under capitalism. (never seen a capitalist society where capitalists are the majority, send me a source if there’s one).

The Proletariat: AKA, The Working Class, The Workers, or "The Majority ". The working class is the class under a capitalist society where they sell their time to work for some bourgeois fuck for a wage (examples would be: factory workers, minimum wage employees, and pilots of a flight company). They relate to the “means of production” as the machine’s gears and/or cogs, while they’re important to the machine, they’re easily replaceable once their “value” to the owner of the machine runs out. They’re always the majority under capitalism (never seen a capitalist society where workers are the minority, send me a source if there’s one).

Other Classes to take note of:

The Lumpen-Proletariat: While classified to be “working class” like their normal counterparts, they don’t relate to the means of production at all (imagine gears and cogs that don’t fit in the machine, so they get tossed aside almost immediately by the owners of said machine). Some of them are desperate workers just trying to get by in a harsh land while others are basically hindered by some condition that prevents them from working like their normal counterparts. Examples of lumpen workers would be members of a crime syndicate, prostitutes, the disabled, petty thieves, those that live off welfare, and the unemployed.

The Petite Bourgeoise: Somewhat of a wild card class. Basically, they can either be self-employed people (like freelancers), own a business that has all of their wealth comes from their labor (like independent plumbers or ya local window cleaner), or owns a small business that hires a few employees but still does work in said business (like the Mom ‘n’ Pop shop or a local small cafe). The majority of them either end up being proletariat (due to the capitalist system favoring the big boys over the little boys of the “competition” and resulting in the latter being run out of business) or puppets bought out by the big boys, but, if they’re lucky and that’s a huge if, a few end up becoming big boy capitalists.

The Enforcers: Mostly a tool “class” that usually helps serve the interest of the bourgeoisie (capitalist) or proletariat (socialist) depending on the state society. Examples are the police (secret or not), propagandists, and mainstream media and news outlets.
