I don't think it has changed that much since the 60s. There was always a certain percentage at the top of the tree making money out of it. We live in a capitalist society. Bound to happen. As far as the UK is concerned the only thing different that has happened is a group of indifferent lively chantey singers got a million quid contract, but they've probably spent that on holidays by now and things are back to normal. To hit the very top in folk you really have to sell your soul to the devil, but thankfully not many do that.
