Massachusetts has a relatively strong economy and high quality of life. Boston's status as a second-tier world city is not in doubt. But I'm puzzled why every other city in the state of considerable size (at least 50,000) is in steep decline and can't generate any type of economic development. Fall River, New Bedford, Worcester, Lynn, Lowell, Lawrence, Springfield, and Holyoke have all been struggling for years and the state has pretty much given up on them.
I guess I'm wondering if this situation is unique to Massachusetts or if there are some other states with a similar problem- one major economic center and a bunch of struggling cities?
