I certainly agree with his opinion about that particular school. I have never heard of collection buckets in a MA school before. It's shocking for a place where they charge so much, the phrase for these kinds of places is 'McDojo'. That's not a comment on the quality of the instruction, but rather the focus on selling a product.
I would like to point out however that this is not a picture of every MA school out there. I personally failed 3 of my gradings on my way to my black belt in TKD and almost every other student failed at least once before gaining their black belt. It was a tough learning experience but even in retrospect, I think it was worthwhile.
