I'm not saying entrepreneur equals crook. All the crooks in the music business are of course some kind of entrtepreneurs, that's what crooks do, but not all the entrepreneurs are crooks.
"Entrepreneur" is one of those words like "engineers" which means a lot of different things. Some engineers fix broken washing machines. Some build nuclear power stations. Some we need, obviously. But our kind of music isn't going to benefit by being hyped up big and exploited. And I doubt very much if that was what Joan Baez was on about.
