Well yea, but I think the high minded discussion is good as well. Its not that any one country will ever be X or Y ideology, but having good guiding principles helps to make sound judgements.

I have studied each of the modern ideologies a bit, and Modern Liberalism is a good blend of both Libertarianism and Socialism. Rawls is a good source if you're interested in perusing, https://en.wikipedia.org/wiki/John_Rawls

I have to say tho, I see a pretty heavy trend towards libertarianism. Particularly among my peers in the Bay Area and their idols. I find it pretty annoying because they are the pinnacle of privilege and have embraced a ideology that alleviates their "guilt".
