I don't think this is a problem cured by more money

There are deep systemic and cultural issues that cannot possibly go away on their own with a little capital injection.
I don't have an opinion on increasing or decreasing per se. First Nations is an umbrella with hundreds of different cultures and shared experiences beneath it. There is no single approach to fix what they used to call "the Indian Problem", but what broadly manifests as all the tragedy of a colonized, marginalized and discriminated population. Culture takes on a momentum of its own independent of the root causes of change. As plural as the experiences of aboriginals are, so to must be the solutions to end the inhumane marginalization that is happening to these Canadians across the country.
