Many have spoken out against Harvard in its past 375 years, including Senator Scott Brown, Woody Allen, and Cornel West. Do you agree with their criticism? What do you think?

It is both. There are few things that guarantee success in life but the first among them is Who You Know. Harvard provides a place and an opportunity for the future leaders of the world to meet and get to know one another. Like it or not, virtually every single one of the people who graduate from this school will have a greater influence on the US and the world than the combined student bodies of any one of Massachusett's public "universities". They are elistist. And why not? Is freedom of association not a right in America?

Both/and

Yes.  The latter understandably leads to the former.
