RI receives a substantial sum of taxes (income, property, sales), and the residents also support (and grow) other RI businesses. It's a pretty good deal, when the realistic alternative is that those individuals will neither live nor work in RI.
Realistically, Pawtucket will not attract many new residents while allowing some existing RI residents to improve their earnings marginally. There's nothing wrong with people making more money by commuting farther, but the increase in tax base is not likely to be large at the same time those individual increases are being heavily subsidized by existing RI businesses and citizens.
