But the students who apply to Harvard and fail to get in probably go to schools that are only a little less prestigious than Harvard, instead. Like, I didn't apply to Harvard, but I did apply to Princeton -- and got rejected. I went to Williams College instead. If my income is similar to a Princeton's student's post-graduation, is that because I did it all on my own, or is it because Williams is also a highly prestigious school that provides similar benefits to Princeton, albeit perhaps a bit less?
Steve Case and George Steinbrenner both managed.
No. People who apply to Harvard and do get in, but decide to go to some other college do as well as those apply to Harvard and do get in and go to Harvard.
The ability to get in to Harvard predicts outcomes, actually going there does not predict outcomes.
