I'm not convinced that the change in political climate would lead to a class struggle that would be strong enough to spawn a folk revival. I take a more dystopian view where the emerging proletariat/ underclass would further entrench themselves within the banality of the media, relying on McDonalds for sustainance.

Even at the turn of the century the class difference were often a matter of life and death (read Tressell). In this century the alternative is death by junk food and brain death by the entertainment industry.

I think the folk revivalists would be more like the latter day Winston Smiths, trying to open the eyes of the proletariat to their lot.
