Depends on the job. If you've got a simple, mechanical job that a trained monkey could do if monkeys were more intelligent, then, definitely, you'd want folks who'll slavishly adhere to whatever task is assigned -- the folks who'll spend all night doing SAT prep problems would be perfect hires. But if you want to train innovators who'll actually advance their fields -- whether we're talking mathematicians, scientists, engineers, doctors, or business leaders -- then you'll want the folks who'll pursue such things on their own initiative along with the talents they've developed due to that intrinsic motivation. Elite non-innovators can have their place. In science/engineering/math, they won't be leaders, but they can still be effective researchers with strong publication records, reliably churning out decent-quality papers. In medicine, they can be great practicing doctors. In business, they'd be reliable middle-management types. Still, it'd be weird for a top institution to only have middle-management types.
