As others have pointed out the majority of NDNs live well below the poverty line. And, anyone who works at their casinos is not making much more than minimum wage; I know, my son-in-law works at Foxwoods.

what are the "have" Indians doing to help their own "have-not" Indians??

Why should the onus be on them anymore than the rest of society to help each other? Should we ask what are Pilgrims doing to help their own? etc.? Lots of NDNs find not much in common with one another just as a white liberal may not find much in common with a white(is there any other kind?) skinhead. Should they be called to task for what they might be doing to "help their own" if "their own" means skin colour or ethnicity? Not, IMO.
