The big takeaway here is how municipal politics works. There’s a tiny number of people - largely volunteers - working on the issues that have a huge impact on everyone’s daily life - and how much they deal with a very motivated and angry opposition all day long. The opposition size is never truly known, and the problem is it usually feels enormous and is actually tiny. It is not unusual for big city projects to be shut down literally by the angry screaming of a dozen people.
Lest you think this is just a small town thing, I have first-hand experience working in a local committee when I lived in Houston, and it was basically identical to what this author described.
Care about our national housing shortage? In nearly every city there exists a small angry mob that works to block every development project, and this job tends to be loudest and angriest about middle to low income housing and apartments. If you want that to change, the single best thing you can do is show up to local meetings and say “I support this apartment building.” Even better if you can mobilize a few friends. You would be shocked at how little it takes to have a big influence.
