The value proposition for living in Boston grows more headscratching for me by the day. The rental and housing markets are truly insane, but the city doesn't really offer anything you can't get in another major metro area, unless you need/want to live in the leading life sciences city in the country.
I love Boston and generally enjoy living here, but I can't imagine staying for more than another 5 years or so...there are other cities in the US that offer just as high if not a higher quality of life for a much more affordable price point.
I'll just leave this here. I could go on for pages about this subject, but EdMc's pictures are far more eloquent than I could ever hope to be.
