Or, shudders, they have gone to school and gotten a degree in Arts Administration, meaning they are full of “theory” about how arts organizations “should work.” Then they go out and ruin them. They are taught to make a profit.
I also recommend reading the book Teaching Genius, a very aweful portrait of Dorothy DeLay, who had a lot to do with how the system worked or continued to work. The main influences in the history of arts management were Sol Hurok, and Columbia Artists Management. Columbia is responsible for much of the damage.
