I don't know how forced it was but I know many such relocations were done near here into the 70s.
When my family moved to Utah in the late 60s I went to high school with several Navaho who were in the Mormon Church's
Indian Placement Program https://en.wikipedia.org/wiki/Indian_Placement_Program . I got to know some of them, seems like about half were happy enough with the arrangement, but half were not.
And the
Intermountain Indian School https://en.wikipedia.org/wiki/Intermountain_Indian_School just up the road housed a couple of thousand. I don't know of any accusations of abuse there.
I think most of the people doing this believed they were doing best for the kids, but am not so sure it was always the case.
