Norwegian here. Healthcare isn’t entirely free here, but it sure is affordable. I’m not sure if entirely free is a thing to strive for. A minor cost helps upper the bar slightly, so people don’t annoy the doctors office with stupid minor stuff (which is already happening).
Higher education is also not entirely free, just really cheap. But as long as you get a stipend (everbody that finish their study does), the state end up giving you more money than you spend. So yes, free higher education is great, I feel sorry for americans.
Affordable housing: should that be free? I agree it should be affordable though, but how can that be achieved? It’s basically the free market deciding
