This suggests that the "wealth gap" (Endowment gap) of colleges in the US is increasing, probably at an accelerating rate. This is probably not a good thing. I wonder how much of a difference the tax-exempt status is a factor in the growth of e.g. MIT's endowment. Was this tax-exempt status ever in jeopardy? It's unclear from the article whether this status was part of the failed anti-trust suit, but the article does seem to suggest this is the underlying problem.
