On AI-generated Essays and Private Education

A month ago, I was asked to proofread a whole set of college admission essays generated by AI, which I declined in good faith. I thought that was the end of it, but apparently I was wrong. Just a few days ago, I was assigned a new student who proceeded to turn in the very first writing assignment, completely written by AI. At that point, why even bother? The parents should save money on a decade worth of private education and just buy their children a building or something.
