A few different reasons from what I’ve gathered lurking around various communities. Full disclosure: I’m not in the aviation industry, just someone with an interest.

• Controllers are extremely professional almost to a fault. If they walk that puts more strain on an already strained system which endangers the public
• Related to this, the public is still generally on their side or at least sympathetic to the situation. If they strike and there’s an incident, they will be blamed. the admin would love for this to happen. They’re already trying to turn public sentiment against them (see comments by the transportation secretary about starting salaries which are demonstrably false).
• Their current union is not in favor of any work action
• They are already being threatened with firing if they strike under the guise of sick leave
• For most of them, this isn’t their first shutdown
• The controllers that’ll feel the pinch first are those working at smaller, less busy facilities. One or more of these shutting down completely won’t impact much.

Again this is just my observation. Anyone with more insider knowledge feel free to correct me.

many public schools are bad due to poor funding, many are not. I do t blame any parent for wanting their kid to get a good education, but the more those who can simply turn to private schools, the less political will there is to fix public taxpayer-funded schools.

I’ll admit my answer was a little presumptuous in assuming the reason had to do the other students, but as pointed out plenty parents opt to send their kids to expensive private schools when public school is free for all. Can’t totally blame them when public schools are woefully underfunded in many places.

Doesn’t want her mixing with the poors and brown people in a taxpayer-funded public school.
