The Nordic countries are the obvious choices for how to run a welfare state, but I think most of Europe has come to terms with ending their empires better than I think the US is/will.
I am actually being a bit more pessimistic than I should be as the domestic Biden agenda would be really good if it gets done, I just have serious doubts about it and the constant invoking of these insane little barriers to change our democracy has allowed are bad signs (the parliamentarian, cloture and a bunch of other dumb senate crap).
I mean at the end of the day, we had an election between two guys who had melting brains so it is hard to take an overly optimistic view, but I am watching for what happens over the next year and would be very happy to see infrastructure and a voting rights bill.
