A lot of people sold their land to the nation before the land claim. The Oneidas were never very interested in houses, more interested in acquiring land. The sales have slowed down. They honestly believe that this is land that they were cheated out of and this is land that they think they can have awarded to them. But you can bet that if the Oneidas had paid taxes on those casinos they never would have been able to acquire as much as they have and wouldn't have expanded as quickly because they wouldn't have been able to afford it.
Taxes are expensive.
