I came across of Socialism 101 and, as I'm reading through it, I think that I see what made communism so successful. They managed to convince"ordinary folks" that they're under dictatorship (by their bosses). They put equality between "has more power" and dictatorship. Then they argue that as long as we have any classes there will be one class ruling over the other ones. So they claim that the ruling class should be the working class, it should be a dictatorship of the working class. But the mistake is that what dictatorship means changed in between. In the first instance it was about "having more power than" whereas in the second instance it was about working class taking freedoms of factory owners, bankers, ...

Rhetoric fallacy, I would say! 🤔
