Throwing money at the First Nations is not going to help them improve their quality of life, it's just wasting our tax dollars. A lot of efforts to help are viewed with disdain, partly justified because the initiatives are ill-conceived by people who do not understand the Indian paradigm, let alone aspirations.
I say, let's pay our outstanding debts from treaties, and leave them be! We have tried "development" from above, it obviously does not work (and indeed this asbestos repair business is yet another example of bandaging bullet wounds), so lets let each group go their way and develop themselves, with the resources they have a right to (the treaty money). If they choose to build casinos, that's their business, not ours.
But since policy dictates we must improve conditions for the Tsu Tina (even though asbestos, I read somewhere, was 1000x less likely to cause fatalities than car accident deaths), I don't think it's reasonable to leave them homeless during the repairs. And where else in Calgary is there room for 600 people, with a vacancy rate of almost zip?
