"The huge folk festivals would not be happening if people did not profit. If you can not see it the fact is just hidden."

The majority of UK folk festivals, even the big ones, are run as not-for-profit organisations. After all the expenses are paid, whatever is left over (if there is anything) is ploughed back into the following year's festival. Many festival directors don't draw any kind of salary; some festivals pay some staff a part time wage. I can only think of one person working for a UK folk festival as a director who draws a full time wage, and he is actually paid by the local council. Yet many people work 30, 40, 50 hours a week on their festivals, as a "leisure" activity, outside of their actual jobs.

The festivals continue to happen because people are passionate about folk and passionate about the festivals, not because they are getting rich.

There is nothing "hidden" here - an organisation's legal status as a not-for-profit means that it has to be run this way. So you are, once again, talking rubbish, Conrad.
