I love the analogy to United Airlines.
Still, I too wonder if students will value their educations as much and work as hard if they are not paying. I also wonder if MIT could become still more unresponsive to student needs/desires if no tuition was involved.
Perhaps one solution to the former would be to charge a tuition based upon your record/grades so far. Or alternatively, just pay students that get good grades!
