Truly, that is prevalent form of political organization in the western world, difference is just in the degree of “socialization”. U.S., for instance, has socialist universal system of public education. Some might take it for granted, but many thirld-world countries cannot afford that, just as many developed countries couldn’t just a century ago. Don’t forget socialist law enforcement and public safety, as well as socialist national defence. Is just the word “socialist” being stigmatized by those who protect corporate profit margins under pretence of “freedom”-fighting.
In general, as you’ve said, American “media-induced political ignorance” shines through in that post. From the standpoint of political science there’s clear difference between “form of government” and “economic model”. And all those are not mutually exclusive. You can have totalitarian capitalism, just as easy as totalitarian “communism”. Or you can have so-called Scandinavian (or, more broadly, Northern European) Model: socialist-capitalist democracies (I am generalizing, of course), that routinely ranked higher than U.S. in “The Economist”'s ratings of political and economical freedoms (note, that is a conservative publication).
