This cuts both ways. Very well-known, competitive private schools conservatively financed have a waiting list a line around the block long and can enforce high standards. Private schools that are struggling for funding can find the compromises more tempting than they can bear. Finding that difference in the moment instead of as past historical anecdotes is surprisingly hard, though if someone has come up with a formula I’m all ears.
This is the failure mode of a system exceeding its capacity with no ability to apply back pressure. Slowly failing as gracefully as possible, eventually passing everyone.
