What if, like say corn subsidies, teachers are guaranteed to be paid enough to be able to buy an average price house within a mile of the school they work at? What if we had to stop bombing one country, let's say Yemen, in order to pay for it? Rhetorical.
These are the most trusted people in society, much more so than the police and politicians, and should be compensated commensurate with both their responsibilities and experience. You gonna leave your 5 year old at the police station or city hall all day?
