For any commies on this board I'd like to clear up a few things to make sure I understand your ideology correctly.
If I own a small business that hires no one, then I am not a capitalist. But the second that I hire someone to say, sweep the floors or clean the dishes, then I am a capitalist exploiter.
If I am a worker in a factory, then I am a proletariat that is being exploited. However, if I use some of my wages to buy stocks in that factory, then I am both a capitalist exploiting the workers AND a proletariat being exploited by the capitalists.
If the communist society comes about, then I can own a house with hammers, saws, lathes, 3D printers, and so on, since those are personal property and thus can be owned by me. But if my neighbor wants to use some of my tools to build something, I either have to let him do it for free or turn him down entirely, since demanding compensation for him using my tools would be exploitation and would make me a capitalist exploiter.
If I lend out my personal property to some people, and those people use that property to build a factory, I am not entitled to any share of that factory if I did not personally assist them using manual labor with the construction of that factory under Communism.
If I am the CEO of a large corporation, but I do not have any stocks, then I am just another proletariat being exploited by the capitalist class using wageslavery. But if I DO own stocks as a CEO, then I am part of the capitalist class and am exploiting others.
