I'll bite on this (for context my wife and kids are all Native American, I've spent enough time on the Rez and one of our family members is the Director of the BIA so I've been able to learn a little bit about this ). What it comes down to is that many native populations are 1) extremely underprivileged - a lot of the communities struggle with just basic access to running water, schools, etc. And 2) the tribal populations have also been diluted significantly due to things like the residential schools, theft of children and people leaving "the rez". WRT #1, when your community can't give you the same baseline opportunities as say your average middle american WASP community then it's a naturally steeper funnel to climb out of. So you just get raw fewer numbers of people who are even remotely capable of getting selected for UPT by that age - I'm not saying Natives can't hack it but that often they start behind the goal post instead of at the kickoff line in terms of opportunities and the resources just aren't there to foster the the natural talents/inclinations/traits that Natives might have that would normally make them a great candidate had they grown up in other circumstances. The actual talent of many Native individuals I've met is impressive though - they are naturally extremely brave, sharp and witty. It's no coincidence that our tribe (Mohawk) is known for their steel workers - guys who built the Empire State Building without harnesses, ropes or anything - literally just scaled steel into the sky and then did roll call at the bar end of the day and cheered to the men who fell that day. Some real courage and skill. WRT #2, a combination of the residential schools and skin leaving the rez in search of better opportunity has ultimately bred out / white washed the Native population. From what I have seen and learned, there literally just aren't even the raw numbers to make this a viable recruiting opportunity. By the way this is not even to speak to ancillary points like the cultural challenges of the drugs, gambling, smugling and gangs that often funnel young Natives onto the wrong path (which itself is actually not a Native problem but one that 19th/20th century Americans have given them). I think when you have a competing source of work/recreation that also would help the USAF focusing on Native communities. By the way huge props to you for identifying and recommending Natives for this, a lot of people wouldn't even think twice about this group of people who has given so much to our Nation and really got the shit end of the stick in so many ways.
