In my previous comment, please note when I say "hip-hop", I am not referring to music, but culture. Nonetheless...

I grew up in the south. My father was literally a clogger. I'm no stranger to folk. But, I am extremely skeptical of a lot of it's history. The mid-century folk-revival era did a real number on our conception of what's really there culture-wise. Behind the curtain, I am honestly afraid it's mostly puritanism, shame, and self-conflict. It's interesting but I think calling it a cultural movement is mostly romanticism. In terms of music, we could delve into details for days, and break down the whole history of hip-hop and jazz, and I do encourage that. There's a lot of good music there. But, I'm afraid it serves essentially the same end in terms of culture; a terribly familiar story. Hip-hop exhibits the whole of the cultural dynamic fairly explicitly, and is internationally renowned. Folk is mostly replicated in parody.

EDIT: Another thing to add... I think most people would be surprised how many contemporary folk musicians (young ones) would actually agree with me. They eventually are challenged with contending with things like: Did folk come from slaves? Or the working class? Or the fraught relations between the two? And is it reconcilable? Where did country music come from?
