Wow. This is part of why Boston is literally collapsing as we speak.
Boston's not collapsing. It's doing very well, and they're putting up tons of housing. The problem is that middle class families are leaving, and being replaced by a) immigrants and b) empty nesters, 20-something Carrie Bradshaw wannabes, and DINKs (often homosexuals). That's actually a great combination for the city's tax base and for companies looking for workers, but it means the population declines without a change in housing occupancy and you lose the sense of being a real city and not a playground for the rich.
