Will the U.S. ever become a social-democratic country?

I do not know, in response to the OP, but I doubt it is likely to occur.

Solidarism - a sort of left liberalism exhibiting individualist values and corporatism - seems a bit more likely to me than social democracy here. Though I reckon social democracy would be very agreeable to at least a third of the population right now, and in practice nearly exists in some American states, it is not an ideology wholly compatible with the fabric of U.S. political culture - a culture that is overwhelmingly dominated by variations on liberal thought. In that respect I am inclined to agree with the resident libertarians.

Where I disagree with them, however, is with their claim of social democracy and socialism being completely incompatible with constitutional republicanism or other "founding values." Such leftist ideologies could be imbued with American characteristics so as to effectively set them apart from their counterparts in other parts of the world. But anyway, for the foreseeable future I anticipate social liberalism will remain the dominant ideology of the U.S.
