The average cost of tuition (not room, board, books, travel, living expenses) for private colleges is about $35K/year. At the more expensive private colleges it's twice that.

Are people really going to pay that much for 15 hours of Zoom lectures a week? I doubt it. The primary reason parents are willing to pay that much is not for the education (with some exceptions) but for the credentials, the networking, and putting their kids into a cohort of successful, like-minded individuals from which they can choose an acceptable mate. And of course to get that 18 year old bundle of hormones and poor judgement out of the house but still in a relatively safe environment.
