What they need is a sustainable economy, and they pretty clearly don't have an economy at all, all of it is basically handouts. Their members that do generate income move off reservation so they don't have to contribute (but, of course, still keep all the benefits that comes with status), so it ends up that the only people contributing are the Canadian taxpayers, basically forever. Their own people don't care, so why should we? They need to get their act together and take care of this stuff themselves, like every other Canadian. Failing that, if they can't support themselves in the environement, they need to move somewhere where they can do that.
When you read this story it is all about what other people are not doing, but what is glaringly absent is what THEY are doing about it. I don't have a problem with government stepping in and helping out a community in an emergency. It is when that emergency is a permanent state of affairs and the community itself is doing nothing about it except casting doefull eyes, that is when I have a problem. I have no sympathy with these folk. They need to move, and that is that.
