“I think that unless we can find a way to solve our housing problem, we cannot solve the income inequality problem,” said Barry Bluestone, an economist at Northeastern University’s Dukakis Center. “Because if you think about income inequality, it’s not just, ‘Do you have a high income or a low income,’ it’s ‘How much does that income buy you?’ And so the real problem in Boston is not only do we have the fourth-highest degree of income inequality but we have the second or third highest cost of living.”
