Ryerson did not architect the residential school system. He gave his advise. And at the time, it was an effort to educate the native people. I went to highschool and played hockey with one of those who went. He was a great guy, a very intelligent person and a fantastic hockey player.
He went home to the reserve for Christmas one year and came back with two black eyes. Seems his own family beat the hell out of him for being "white"
I've also met a teacher who have taken contracts to teach on reserves. None of which went well and the teacher soon resigned in defeat.
So...to summarize...Ryerson did NOT architect the residential school system and the native people are quite responsible for their circumstances.!
