If killing people is your bar for descending into tyranny then capitalism is guilty of the same thing. The whiskey rebellion happened in the US shortly after it’s formation and that was over paying taxes to the capitalist state. You also had the various government slaughters of workers striking whenever they tried to get a better deal from their employers
I'm not advocating for capitalism, I'm just against socialism/communism because it fatally corrupts people's minds - watching local movies from this era is painful, as you can see the horrific distortions it imposed on the people from above. I mean stuff like parents teaching children to never stand out, never excel, never strive for more, never be different - in a panic try to protect them from state-mandated harm.
