I'd be a lot more open to this if the Socialist countries and the Capitalist countries hadn't spent the last half of the previous century at each others' throats.

In any event, we have a term for New Dealism and what Norway is and everything similar: Liberal Democracy with a Welfare State. The problem is, in the US, the Republicans have been insulting that model by calling it Socialist for so long that people think that's what Socialism is and then insist they are Socialist when the idea of regulated Capitalism and a social safety net sounds good to them.
