In Ohio your property taxes get reassessed periodically. So as the local market goes up so does you tax burden. People really do get priced out of their home, sometimes priced out of the area entirely, especially if they are living on a fixed income.

Maybe, but that's not always the case. In the US, powers of eminent domain have at times been delegated to private entities. If there's a clear public benefit for seizure of land, sometimes the landowners don't have much of a choice.
