You're asking about barriers people face in trying to go back? There are a lot of social issues, such as overcrowded housing—it is difficult to get your homework done when you have ten people living in your house.
One time I taught in Port Alberni in a building that used to be the residential school. I taught in the college sector, so I was working with adults. A lot of those people had had bad experiences in that building. I wondered how we could expect adults to learn in a place where negative things had happened. It often brought back the experiences that people had in the classrooms. There are a lot of these colonization troubles that people are still experiencing. Some face them on a daily basis.
