Education is weird as a product, because you're delivering the same experience to students but they each pay a different bespoke price. Sometimes schools even pay their own customers!
When a rich person sends their kid to school they get charged full sticker price. Then schools use some of that money to subsidize the educations of the other students. Given those dynamics, there's really no reason for the tuition sticker price to ever go down unless the uber-rich can't afford it anymore, because the actual price anyone pays is floating and can be whatever it needs to be for them.
