It is exactly for that.

I guess everyone is forgetting that the bulk of "critical infrastructure" jobs all make under 70k a year(not counting overtime and such). Force them all to move elsewhere causes shortages in critical positions. The biggest recent example is snow plow drivers, that's only going to get worse and worse every season. We will see shortages across the board soon and already are. I mean a Worcester firefighter or police officer couldnt even afford to live there.
