You are making some mental gymnastics to ignore the historical oppression and continuing fight for legal rights. By your flawed logic, someone who inherits a building also have put no monetary investment on what they are renting. You might as well also say that holocaust survivors won the lottery, by that logic. Indian tribes, and every minority that managed to gain any stop-gap benefit, have to invest a lot of effort and time in maintaining their immunity/rights/etc. And this obviously greedy move, make that work harder in the medium/long term for them and every other tribe. So in a way they are putting in a investment.
