A prospering but shrinking city. What does that say about all US cities? "Gentrification is roiling Somerville politics, and unfortunately, the local perception is that Somerville has had tons of new construction and the solution is to slow it down. The truth is that just like everywhere else in Greater Boston, Somerville really hasn’t had much construction relative to demand, and that’s why prices are soaring. The perceived link between building and gentrification tends to generate very counterproductive local backlash politics when what’s really needed is a bigger and more regional approach." In this instalment of Slow Boring, Matthew explores how the US city of Somerville has transformed from a working-class town into a shrinking, yet much richer residence.
