And, interestingly, we did not do things like they did in the Soviet Union (which was never really socialist, anyway, except in name... but not enough room for that here). Most of the programs that FDR implemented started life as part of the Socialist Party's platforms of the late 1920's to 30's. Because of Roosevelt's popularity and longevity, the Democratic Party crowded the Socialists out nearly entirely, leading to their breakup and eventual reorganization. And that, really, explains the current divisions between Social Democrats and Democratic Socialists in the current parlance.
