Native Americans are a complex case. I'm no expert, but by and large, they seem to have bred into the populace. It's pretty hard to find anyone with close to pure native blood.
As for other groups, there was a different kind of selection process in terms of who got here, for sure. And many Black groups will remind us that over the years, the Asians that immigrated here were often the richest and most educated.
Still, the Black situation and the connection between slavery and the current situation is far from clear or linear. For example, crime used to be less of a problem among Blacks. Or there is the interesting question of whether the Great Society and its legacy have helped or hurt the Black community.
Additionally, other minority groups have claimed that Blacks have never done what they did to succeed: create strong communities that support community businesses. Jews and Asians, for example, have talked about how money was supposed to recycle within their own community a certain amount of times before it ever leaves the community.
I really have no idea how America can best move forward to deal with the problems facing Black Americans.
Yeah out of the 198 million or so people in the US with native DNA only "maybe, maybe" 800,000 of them have anything even around 70% DNA.
But there are still a couple reservations with honest to goodness "Ingines" if you are still so inclined to find them.
Though it does make a good point; on the reservations or villages/whatever where the NA's have bred so much with others as to be indistinguishable; kind of hard to claim it's "racism against Natives" holding them down when they are still having the same problems when they are now essentially all "Johnny Depp".
Though you could make the same argument for black people in the US to some extent, average black person here has 20-30% white DNA.
1/10 has 50%.
Both blacks and NA's have bred out/in a lot over the years.
There's also the fact we've had a few depressions, civil wars etc....most wealth in the US actually comes from the last 40 years so slavery and even most of the oppression they've faced over the years has less affect than you think.
Some instances where students do really well they try to replicate it elsewhere and it fails.
One of the consistencies is that the black students who tend to succeed a lot are of Caribbean, Nigerian Ibo/Tutsi kind of heritages.
Maybe the rare black person who doesn't do well in life really just isn't trying that hard.
Hell; maybe it just comes down to women; most black guys still get laid.....why would they want to change that to a system where in order to get the same women they are already getting they have to work 90 hours a week, get four years of college minimum, go on a diet and get an 8-pack going on.
It honestly just wouldn't make sense accept to make things harder for yourself.
