The point I was trying to make is that people pay $250,000 and don't get any kind of special education. Harvard doesn't give them anything except an E-ticket.
Again: it might be worth it. But that's price gouging. At some point, society might wake up and say "You're really just like everyone else. Your resume doesn't actually impress me. Tell me why you're really special."
And the Ivy League grads will stare and have little more to say than: "Did you read my resume??? I went to Harvard!!!"
An Ivy League degree is only "special" because previous Ivy Leaguer's treat it as special. Outside that group, society doesn't really consider it that big a deal, although there are still those that don't know any better.
At this point, Ivy Leaguers still occupy enough important positions to make it "useful". That may change in the future, but not in the next few generations.
