Opportunity Knocks For Greater Boston Cities, With A Potential Cost

SOMERVILLE, MA - MAY 9: A wall mural is pictured in Union Square in Somerville, MA on May 9, 2018. A new federal tax break designed to boost low-income neighborhoods could subsidize investment in Union Square and other already-booming corners of Greater Boston. The program could bring much-needed investment to struggling corners of Massachusetts, but some worry it will simply subsidize development thats already happening, and could accelerate gentrification in some neighborhoods, increasing the chances that residents are pushed out.
