perhaps YC should think of becoming like a business school. Most business schools charge upwards of 100k for two years, and most students borrow that from the federal government. YC could instead "charge" half that amount, teach all the major business principles that one needs to know in a few months (which could basically be teaching pg's essays to a class audience) with the caveat that all or most of the tuition charged will be returned as seed investments to the students at the end
