Also I think the most important reason for going to MIT is that you stop worshiping MIT. MIT is a really, really weird culture, and one of the things that you learn at MIT is to hate MIT (google for IHTFP).
You need to learn to hate MIT, because if you "love" and "worship" MIT, you aren't pushing it or yourself to be better. By contrast if you "hate" MIT, you are constantly thinking of ways to make it better. Also, MIT people tend to be cynical people. One thing that I learned at MIT is don't believe MIT propaganda. This is an important lesson, because if you are a part of the organization, and you start believing your own marketing, you are doomed.
Also if you want to get involved in MIT, you might consider joining the MIT Enterprise Forum.
http://www.mitef-nyc.org/ One reason I post as much as I do is that MIT does a good job at making the "formal curriculum" available to everyone (see OCW), but I think it's important to make the "informal curriculum" also visible.
Something that is odd about this conversation is that I think that Rutgers does some things better than MIT does. Rutgers is better at teaching mathematical finance than MIT for some curious reasons.
