Most people around here live in Jackson county Michigan due to the lower cost of living here but work in Washtenaw county where pay is better.
We have more-or-less the same dynamic around here. Pay is better in Boston, but the cost of living is astronomical, so people tend to live in the surrounding suburbs and exburbs. And now the cost of living in those places is celestial as well. One has to drive at least an hour from Boston to find anything affordable.
