I’d be surprised if this wasn’t already happening, considering that the Federal Government gives special preference to Eskimo and Indian-owned business at the contracting trough. Even blacks and women have to wait while the Native Americans get their fill.
And these business have preferential hiring of “their own kind,” which means if you are not a member of their tribe you have no chance of getting the government job they are seeking to fill. How this is not blatant discrimination based on race and ethnicity is beyond me.
