I'm probably biased being Canadian, but I feel a lot of Americans talk about social democracy like it's this ideological utopian grandiose dream that's never been tried or achieved.

But in reality, there's plenty of countries who've done it for a long time and had great success with it: Sweden, Norway, Denmark, Netherlands, Finland, Iceland, Belgium, Canada, Ireland, New Zealand, India, Japan, Taiwan, South Korea, Singapore, and Hong Kong for example.
