I am partial to that argument, at least in the interwar period the US masses and intelligentsia were enamored with the USSR for it was new and the atrocities were not widely known, so we got the New Deal. I don't think that applies to the post-WW2 period and the fact that the US was the only industrial nation left unscathed was the real prosperity driver.

But it is all moot in the world of today where the US competitors are not providing alternatives for people to strive for. Russian propaganda of "everything sucks" works wonders to keep Russians docile and it will work wonders to keep the US middle class down as well, ending Pax Americana will do nothing to change that.
