Ethan Stiefel should have been the guy to make a dance company work in the Los Angeles area. But he was thwarted. Why? “Too bad he had to learn the hard way what the rest of us have understood for a long time: Everybody wants a resident world-class ballet company in the Southland, but nobody wants to pay for it. And rather than repeating [oft chronicled reasons] and clucking sadly yet again, how about considering a radical proposal? How about forbidding anyone to start yet another new local penniless ballet company until we’ve doubled our dance audience through a host of development strategies?”
