Things need to be changed. There is a lot of work to be done to get Native Americans to have greater economic freedom. Too much reliance upon government is not good for any people group.
The Shoshone/Bannock Fort Hall reservation is immediately north of my town in Idaho. They have a big casino. Even with the casino, there are plenty of people willing to exist in squalor on the government dole. Morbid obesity is the norm. Alcohol is forbidden on the reservation, so we get lots of drunk and disorderly Native American patrons in the local bars. DUI and driving without a license, registration or insurance are also the "norm".
