But you'd have to argue it, it isn't self-evident that more education is simply better. Look at the number of PhDs who can't secure post-docs let alone tenure track. They may feel some personal satisfaction from the letters after their names, but it's very questionable that "society" benefits from churning them out. Once you educate people to the level of basic literacy and numeracy, say age 16, it's diminishing returns after that.
