By Jove, he's got it!

Stunned silence followed by cheers from me to WBUR's Max Larkin for capturing Boston's relationship with the Chapter 70 aid!

But that’s where state education officials object. They answer that there aren’t many cities or towns in Boston’s position.
State aid is calculated based on how much a city can afford to pay on its own. The fast-growing tax base in Boston and neighboring cities like Cambridge and Somerville make them decidedly unlike other towns which are facing de-industrialization and economic downturn.
Ten years ago, Boston was taking in almost $266,000 in tax revenue for each of its students. In last year’s budget, that number had risen to nearly $400,000 — driven primarily by an increase in property values.
According to state thresholds, Boston now has more than $100 million more than it needs to cover the basic expenses of its public schools. But the state doesn’t ask Boston to take care of itself, instead opting to cover more than the “minimum aid” threshold of 17.5 percent.

Read it, bookmark it, print it out and frame it. I don't recall this ever being captured by a press outlet before!
