Let hear them conjects
Firstly, just know that the formula “democratic socialist” is itself almost an Americanism (although it’s true that Orwell used it). In the rest of the world it sounds suspiciously similar to what the former communist countries of eastern Europe called themselves. And they were most certainly not democracies.
Outside the USA the usual term is “social democracy”. That’s what the Scandinavian model called itself. Past tense intended.
For examples of successful, free, and equal societies, I would suggest that the best examples are indeed in northern Europe, with a handful of special mentions like NZ or Japan. The HDI is surely the best indicator.
Of countries that have historically used the word “socialist” to describe their political systems, with or without “democratic” thrown in, none are places that you would want to live.
