Not the original commenter, but if I was that parent, I’d explain to my kid the amount of money I would be contributing towards their education and expenses if they bring it…and if the don’t bring it. They can make the educated choice then.
That seems to me to be the least likely outcome of that decision.
A common outcome would seem to be a year spent bombing in their classes because they can’t separate themselves from some stupid game to study while accumulating $10-20k in student debt.
