I don’t have a problem with this. There are several successful, democratic nations out there (I’m looking at you, Scandinavia). Capitalism isn’t the best of a bad lot, it’s just been generally more successful in democratic societies, so far.
As for anyone asking how we can transition harmlessly from one economic system to another…it can’t be done. Any such transition is disruptive and difficult. That doesn’t mean it should be avoided. It certainly doesn’t mean it CAN be avoided. It may not happen until capitalism collapses, which is within the realm of possibility. No matter what replaces capitalism, it won’t be a pretty transition.
