The concern is that there are not many young 'uns going to them , and if they don't learn the songs, tunes and dances , what was it all for?.
Any young 'uns that are any good - instantly go to the concert circuit.
They should get Folk into into school - and learn to play enjoyable music skiffly stuff / make their own tea chest base(s)- get them playing music for fun and see what rubs off   
Aye,the big problem was ,lots of us had Kids ,(and worked too
f#¤%king hard / mortgages etc. etc !!! ) but now it's a pleasure to drop in to a Club, where many people who didn't play or sing in their younger days are doing exactly that.
There's always money for Opera, Classical Jazz , and all that sort of stuff , but mention our own roots music and they all become sophisticated and cite that it would be socially devisive to encourage such narrow tastes as Folk Music.
