While the education is one thing (and surely valuable), I think you also have to look at the connections and network you develop at a "name" school vs. other schools. Those are not things you see on a bill, but they are extremely valuable.

EDIT: I'm not saying this can't be achieved at other schools - I didn't attend a "name" school, but the network definitely matters and can be a huge bonus especially if you know what industry you want to target.
