While Dems tout the merits of a Democratic Socialist society, JP Morgan just finished a comprehensive study of the European Nordic countries that Democratic Socialists often call out as the example the U.S. should follow.
The bottom line: copy the Nordic model if you like, but understand that it entails a lot of capitalism and pro-business policies, a lot of taxation on middle class spending and wages, minimal reliance on corporate taxation and plenty of co-pays and deductibles in its healthcare system.
