Interesting. Roosevelt was, I think, a Democrat and NOT a Socialist. He was, however, socially responsible and understood that meant some things needed to be socialized which is, to my mind, different from "Socialist". I can, however, remember my family constantly referring to him as "that damned Democrat" (they were not a fan).
I also remember my grandmother signing up for Social Security as soon as she could after it became law. I think she collected it for a LOT of years after never having paying in a dime. She was a full scale Roosevelt hater. Always found that one to be interesting.
