Social democratic governments objectively have the best metrics for well-being among all forms of government we’ve tried.

That doesn’t mean it’s the best possible form of government by any means but it does mean you need to make a strong case for why your system should be better.

Personally I think more could be done to reduce the power of the wealthy and the state in those countries, so I’d like to see more experimentation to move towards libertarian socialist policies but I don’t think it’s crazy to start with a social democratic foundation.
