Karl Marx had an idea on starting a new idea for the working people. That idea was called communism. Communism is about the workers getting paid the same even when they all work different jobs. This also involved people not being able to own their own land or property. This was Karl Marx idea of communism and he wanted it to be spreaded all over. Karl wanted all workers to be on the same level not have different ways.
This also supported people who wanted to get the money they deserved and weren't getting. Everyone was working the same job and had to under one major owner. This is why Karl Marx wanted The "good guys" were the factory workers who didn't like the way they were being treated and workedlong hours for low wages and less time breaks. The "Bad Guys" are the Factory owners who controlled everything that happens in the factory because they controlled the workers.
