I agree with everything you say and, in a perfect world, all is possible.  However, it would be extremely difficult to  initiate and maintain secondary school systems that work in communities of 300 people or less in the remote north so, like many others who are not First Nation people, it is sometimes necessary for parents to send young teens away to school. One of the difficulties I think is that FN organizations are establishing their own school systems, including a segregated high school in Thunder Bay and other minor schools in other areas.  Not sure, but this somehow reeks of the residential school system which is an area of loathing in this country.
