$50,000 a year for a Harvard undergraduate course exclusive of accommodation and food. Sounds like there's a lot of fat that could be trimmed. Sounds immoral in fact.
Love or hate the top Ivies, they open up doors (or at least fast-track you to the door) that remain closed for a lot of graduates.
If your only goal in life is to maximize your chances at some cookie-cutter prestigious professional job / career, then $200k isn't too bad. The ROI is going to blow most everything else out of the water, as far as education goes.
