There are plenty of valid criticisms of capitalism. Especially the current state of capitalism in the west. It doesn't mean I want to go full communist, far from it. But I'm a mixed economy man. I think certain things should be highly regulated or even owned by the government (and, by extension, the people).
Healthcare is one good example to me. I think private is fine to an extent, but I would never want a fully private system. I think the model in Canada is a good place to start, where public is the go-to option, but private exists if you want to skip the queue and can afford it. The dynamic between insurance and private healthcare in the states makes for a toxic experience for patients, and that serves as one of the primary reasons why I would never want to go fully private. Doctors shouldn't have to fight tooth and nail to get your medication or diagnostic procedure approved when it's medically necessary, assuming the system can reasonably absorb the cost.
Mixed economies are the way.
