Get ready for rents to SKYROCKET if this goes through.  Business 101:  Costs get passed on to the consumer.  Even though our property tax is the lowest in the nation (They just raised mine by roughly 25% so that will change things) our cost of living is at or near the top.  Increasing taxes will only exacerbate the problem.  They probably will accomplish getting their class sizes down though but not for the reason they state.
