Yes, Maine is not much different than the rest of the country in that regard.

I would say is that in small towns, the center of wealth mass is felt in the entire town, even when there is wealth stratification within the town. Take for example, Kennebunk, Kennebunkport and Sanford. Thse are three towns that border each other in Southern Maine (York County). In terms of wealth, Kennebunkport is the richest, Kennebunk is second, and Sanford is third. But within each town, you can tell where the rich families live and where those of more modest means live. For example in Kennebunk, the wealthiest tend to be within view of thr water and by extension closest to Kennebunkport where as the more modest income families live further inland near Sanford.
