I think you are absolutely correct M.
Modern "contemporary folk" is agony to listen to unless one is a dedicated ideologue....It started when the left started adopting the popular folkies of the sixties as banner carriers for the revolution, especially Dylan.

How upset they were when these egoists refused to be compartmentalised.
Most modern folksingers are just as wedded to aspirational capitalism as any political conservative.

Radicals are few and far between, I assisted in running one of the largest folk clubs in Scotland in the sixties, and could number radicals on the fingers of one hand.
I have conversed with all the "big names" from that time in Scotland and some from England.....their driving force was almost always self promotion..... and some were musical geniuses like Gerry Rafferty, some used the popularity of a folk scene which they despised (singing pullovers), to advance a career in show business.....like Billy Connelly. The great Alex Campbell was another who saw his music as a job of work...a transient worker, driven by the need to provide a living for himself rather than any political conviction.
