I mean I'd like to believe I'm some sort of one-percenter, but I don't believe I am. I paid full sticker price for two children and with my third there was some nonsense with institutional aid, but the hit was still way over $25000.
The problem with his central thesis though, I find is the reason behind jacking the price up. The reason isn't to make the school more prestigious, but rather to be able to soak all buyers at the proper price point. You can't state a lower tuition and then jack it up for the children of lawyers and hedge fund managers. You need to start high and then offer assistance to the children of mechanics and plumbers. (I know -- many plumbers are rich)
The funny bit is while airlines and car dealers have to resort to judgment and tricks to figure out your price point, colleges get the FAFSA handed to them.
