Yeah but who in their right mind would want to live in OMA or TUL. That's why its so cheap to live there.
I tell you what, take the whole NY center and rebuild the thing in OMA. While you might save 20k a controller, you won't get the best and the brightest. Plus it would cost the Gov't 100's of millions to move the whole thing out there. Living above the Big Dig I can explain to you how a government project turns into a nightmare.
100k these days is worth crap. But then commuter pilots are on a 20k to 30k payscale so anything looks better. Even the mop boy in a peep show.
