Last week, I linked to a NYT article about the spread of CorePower Yoga: how its business model is contingent upon enrolling thousands in expensive “teacher training” courses, even though there’s already a surfeit of teachers out there. The company makes money from the teacher training, and teachers’ own labor becomes devalued, as they’re encouraged to teacher for less or teach for donations (appealing to yogic principles of service and selflessness as a means of excusing it).
