Selecting for students who have a track record of success in spite of 60-hours of time being "spoken for" is a not unreasonable selection process for students who will succeed at MIT.
The 60h/week figure is what I observed ~8 years ago for my peers to be competitive for our state university that was not MIT or an Ivy. My point is that I think students are being overworked because the requirements are too subjective. A student has to be involved in everything on top of having great grades and scores because the SAT/ACT was the only thing that was even close to being an objective requirement.
