I imagine stuff like monopolies is what a true free market economy would look like, so I wouldn’t say things like that are a sign of illegitimate capitalism. However, that is not the case almost anywhere. True capitalism doesn’t really exist because it’s more or less regulated everywhere, and it’s usually where these regulations fail, where we also see the biggest issues with it. That’s why I’m opposed to people advocating for ending capitalism. In my view that is too radical and narrow minded and will lead to a ton of unpleasant side effects that aren’t even that hard to predict. More and better regulation is the more optimal solution in my view.
