Well, Georgia doesn't have "low" salaries. Maybe lower than NY, but most are lower than NY. Also, when they get there and find the cost of living and the physical dangers I'd bet they'd reconsider.
What's interesting -- from my limited experience with teachers from out of state...is they come to NYC and have a blast for a couple of years. They get "the system" to pay for advanced degrees at Columbia or NYU and then marry well and move to the burbs where they increase their salary by 20% or more.
