My town exempts people over 55 from some school parcel taxes. That is because there needs to e a supermajority to pass bonds and exempting people who don’t have school age children makes them much easier to pass. There is a balance that needs to be reached here. If you take this to the extreme, I could have no children and work while my neighbor has 7 children and chooses not to work.

Those 55+ year olds don't realize who are paying their pension and medical care.

Is that the same issue? Public schools are a public good but compensation/equity/advancement is a private one with private benefits. This isn't an issue of preventing financial collapse but as OP says a matter of "career prospects". The justification for that reason as a public good seems a lot less obvious to me than for public education.
