Know why that is? Most government workers are FORCED to live within their government's entity. A city worker must live in that city. A county worker within the county, and so on. The Ohio governor tried to lift the "residency rule", but last I heard it didn't go to good, with municipalities and unions suing the state, because ultimately they found that premium would be null and void.
In NYS, they want to bring in a new tier that will cut THEIR retirement by 40%. Mine will stay the same, but everybody's health will skyrocket.
