Haha, Phil so true! These yoga schools are just to make money! But some of them are amazing! I had a wonder YTT experience. But there is this one school I heard of, my friend did her YTT from her last month. The have yoga teacher training in Dharamsala by name of Chinmay Yoga School.
I really liked their concept of working. They work on no profit model with only intention of spreading knowledge. They are also recognized by Yoga Alliance. People should promote such concepts.
