I think what it comes down to is this: A&M, UT, MIT, Rice, Harvard, etc are hard to get in to, and graduate from. In order to do that, you have to bust your ass. Have that work ethic. Those are the traits needed to get into (and out of, don't get me started on top 10%) these school. It may say more about the individual's work ethic and grit than the school. The difference about a A&M is that we really teach and take pride in the other education. None of those other schools make that part of their culture. When a higher percentage of your graduates are wired and schooled like that, you tend to win more often than not.
