WITH the academic year about to begin, colleges and universities, as well as students and their parents, are facing an unprecedented financial crisis. What we’ve seen with California’s distinguished state university system — huge cutbacks in spending and a 32 percent rise in tuition — is likely to become the norm at public and private colleges. Government support is being slashed, endowments and charitable giving are down, debts are piling up, expenses are rising and some schools are selling their product for two-thirds of what it costs to produce it. You don’t need an M.B.A. to know this situation is unsustainable.
