The Massachusetts law requiring cities/towns to build high-density housing around commuter rail stops neglected one thing. There's no open space. To build high-density housing, the city or state would have to buy out the existing landowners, demolish the existing property, and then build anew.

They also neglected the effect of travel time on behavior. Back in the day, I was commuting from a rich suburb to Cambridge, and to get to work on time, I had to get up early to accommodate a 30-minute commute to the train station, wait for the purple line and the red line, and then walk three-quarters of a mile. When I saw how little traffic was on the road, I said, "F it," and drove to work in the same amount of time as it took me to get to the train station.

In the Biolab space, it was a little overbuilt, and now it's tremendously overbuilt because of the killing off of NIH grants and subsequent reduction in investment in the biotech sector. I suspect the reason they don't drop the rent is that it would cause a bit of unraveling. You drop the rent; that changes the valuation of your building, which may mean you're underwater on the loan, the bank calls the loan, et cetera, et cetera. Then, similar properties would suffer devaluation and a similar unwinding. And if you agree with the contagion theory of deflationary environments, it'll all unwind all the way through your 401k and other investments. Sadly, the billionaires would be untouched.
