Whigh, you said the same exact thing on the last page, and it's still ineffective on this page.
There's more to a city than housing - as someone who points out the magnificent expansion of Kendall Square every other post, why don't you talk about it here? Cambridge has
twice as many employees in the city in twice as many companies as it did I half a century ago - don't those companies and workers need phone lines, water, and public services, too?
As you point out, the population fell (though is now rising) - but due to smaller household sizes, not fewer houses. The city didn't physically get smaller over the last half century - still gotta provide services throughout to all households, even if they have fewer people in them.
The City also provides more services than half a century ago, like actually giving a shit about infrastructure and public safety, which provides a massive return on investment due to increased livability and desirability.
Lastly, if you'd read the article linked (twice!) on the last page, you'd know the city needs more space for its growing Information Technology Department. Yes, we live in the age of data, but somebody has to
do something with the data, and the City of Cambridge is an innovator in municipal data application. Plus, data has to physically
be somewhere, so they need more room for servers (and generators for redundancy).
Cambridge is a successful, effective city with lots of revenue. Expanding revenue-enhancing services is a smart business move.
