There is two primary classes in capitalism, these are broad catagories, not absolute binaries.
1. Proletariat, those who have to sell their labour to a capitalist in order to live
2. Bourgoiesie, those who own the means of production and hire workers to extract profit from them
There are gradations between them. Petit bourgoiesie are small bussiness owners who arent capable
of living of solely hireing workers, they have to work their company themselves along with employees they hire. Capable being the key word here. If you can live off dividends purely you are not petit, even if you choose to still work there as a CEO or something.
- Classless workers, these are people who are self employed but have no employees. This is very vague. People who sell their labour to companies in this way are just proles without rights. People who run actual bussinesses for consumers arent.
- State employees: These are technically not employed by capitalists but by society and as such do not parttake in capitalist production, and as such dont have a direct stake in overthrowing the bourgoiesie. However, their interests almost always align with the proles in terms of labour laws and wage.
- Lumpen: A derogatory term for people with no class concious potential and the chronically unemployed, homeless people, junkies, nazis, neets.
As i explained here>>1008316
dependent children/young adults do not parttake in production and as such have no class interests in themselves. Their class interest is the same as that of the people that provide for them.
