I think you're simplifying although you're probably on the right track (sorry not punny). West Revere has a middle-class cohort--and they're the ones farthest from the Blue Line, for whatever that's worth. East Revere, bracketed by other struggling communities (Lynn/Chelsea/Everett) of course does have the Blue Line. But that transit is hampered in a variety of ways. It abruptly terminates at Wonderland--well before the Lynn/Salem area that should be its natural endpoint. It's also amputated from other neighborhoods by Route 1A, and the Wonderland blight, and the Newburyport commuter line. Point being: just get the damn Blue Line extended to Salem, and see what happens. It sure as hell couldn't make East Revere any more unappealing.Revere is a great counter-argument to "transit = gentrification"
