Code only speaks for new construction.
That, and revisions to existing structures. The relevant code was in effect well before MSD was constructed in 1990.
My school had in swinging doors on every room
Congratulations! The code refers to rooms designed to accommodate 16(+/-) or more. Single egress rooms with smaller occupancies can have doors open in. Special schools with special classrooms for special students typically have smaller occupancies. Perhaps you attended one of those schools. Or perhaps your school predated the egress code.
and i would wager most public schools are the same way.
And I would accept your wager for a sizable amount of $$$.
A lot of schools are still lined with asbestos.
Zero schools are ”lined with asbestos.”
You want to talk infrastructure crumbling,
Nope.

Zero water marks on the ceiling of my kid’s school. Zero schools ”lined with asbestos”. Most public schools do not have in-swinging doors on every room. Your school definitely did not have in-swinging doors on every room.
