Yoga studios may have started with good intention, I know I started mine in 1992 in order to help people feel better and to find calmness of mind.  But many yoga studio owners soon found that simply offering classes to the masses wasn’t a viable business.  Simultaneous to discovering the need to have more teachers on staff so burnout didn’t happen to the studio owner(s), they also discovered that they could make more money training new teachers than teaching classes. Training Programs generated the output of more teachers which then flooded the market, and yoga studios and teachers both found that there were too many teachers who could not make a living teaching regular yoga classes to the masses.
