I'd be happy with a social democracy that emphasizes a mixed economy with strong social welfare programs funded by progressive taxation. Examples include the Nordic countries (Denmark, Finland, Norway, Sweden).
I don't know how to accomplish that though because the farther we slip into a class dictatorship, the harder it will be to enact progressive taxation. We'd all vote yes to tax the 1% richest more, but that will never be on any ballot for us to choose.
