Mixed social-democratic economies are nice and better than plutocracies, but they have capitalism; they just have other economic forms alongside it.
(Needing to profit isn’t exclusive to capitalism either. Socialist societies also need productivity and profit, because they need to reinvest.)
It’s not a fantasy idea. I grow up there and it’s still working.
It’s not out of beautiful idea either. But sheer pragmatism.
A country will always need those things and those are important things. We might as well invest in them for the long run.
Clearly those are not hip idea anymore. Oh well.
