> Congratulations, silicon valley, you've just re-invented public education! There is a key difference. With public education, the excess cost of the education is born equally by ALL taxpayers. With education that is funded by a percentage of future income rather than a fixed up-front cost, that is born only by the graduates. It means that those not fortunate enough to attend college (or not interested) are not expected to subsidize the students, and it also means that students can choose from a range of different qualities (and costs) of school. Also the original article spoke at length about aligning the incentives of the school and the student. If you believe (I do not) that the only or most important role of a school is to prepare the student for a more lucrative job, then this alignment of incentives is a significant value of its own.
