AP education writer Justin Pope has a solid piece about the growing tensions between the super-rich colleges and everyone else.

Harvard’s endowment - the largest overall - expanded by an amount last year that’s more than Ivy League rival Cornell has altogether. Princeton now has more than $2 million in the bank for every student. Stanford raised nearly $1 billion during its last reported fiscal year alone.

The disparity between the haves and the have-nots appears to be creating a schism in education similar to the schism in American social class.

Harvard President Drew Gilpin Faust added to the tension by getting into an exchange with Big Ten provosts over whether ambitious science research should be left to the most elite universities. Some objected to her suggestion that it would be better for some institutions to focus on social sciences and humanities.

As a handful of colleges get richer and richer, what effect does this have upon the American system of higher education in general? And how will American society be shaped by the education wealth gap?

It’s an interesting and important problem—perhaps the most important problem that Drew Faust will face in her presidency.
