Sadly, this isn’t something new. I moved to Minnesota in '79, my father took a paper route that drove us through three reservations daily (which will tell you where I am if you are familiar with Minnesota), poor housing, cramped living, and hopping from place-to-place was common then.
As I grew up, I made many friends on all three reservations, which at times created some minor tension, but the housing issues never changed.
I don’t know of a solution to this, but it cannot be a surprise that it’s still happening after so many decades. Something MUST change for the native reservations. They deserve better; these are good, very good people.
