Why not just cut out the whole "teaching" thing and mail the student a diploma based on payment of $70,000 and submission of SAT scores? If you get a 1600, your diploma will say "MIT". If you get a 1400, it will say "University of Illinois", etc.<p>That will save millions of dollars on writing software for online course administration (and associated support staff). Then the professors can focus on doing free corporate research instead!<p>And of course, the student is just as prepared for "the real world", and the Universities can build up their billion-dollar endowments and live off the interest. Everybody wins!
