American Socialism

[Alexander the Pretty Good]

In answering the original question, I think it would happen as a result of something along the lines of the Great Depression, probably in combination with a nationalistic and/or xenophobic movement as well. A national-socialist party, if you will. In the name of "freedom" we'll lick unemployment (everyone must Do Their Part) and beat the Japs terrorists. Healthcare and the like will be useful not only as a means to fuel the war machine but also a way to placate any of the masses who hold on to the provincial notions of liberty.

I cannot imagine us instituting significant and lasting socialized public healthcare over the long term because we simply cannot afford it.
