Real talk though. Communism doesn’t automatically lead to authoritarianism. We can have a democratic communist system. 

Capitalism though will lead to fascism. Because it’s all about the bottom line: maximizing profits and minimizing loss. Company profits are prioritized over everything else. Money is funneled into the pockets of the capitalists and they start acquiring each other up until there’s only one. It’s a big game of monopoly. And the working class end up being used and abused until they’re nothing more than wage slaves. And you quickly end up with corruption because money is power. Money rules everything.

Communism kind of gets that out of the equation. The people own the means of production. They work towards a better future for all. They prioritize the needs of the people first. Progress goes towards improving the quality of life of the people.
