@SaphireNY, actually, no, opportunity isn’t in the eye of the beholder. You can argue that prestige is, but that’s not true for opportunity.
As an example, thinking that a school is a Street target isn’t going to make Wall Street banks suddenly come to recruit there. Thinking that Dartmouth or UMich Ross aren’t Street targets or terribly prestigious isn’t going to stop Wall Street firms from coming to recruit at those places or make them stop taking kids from those places. This is true for any career path. Thinking that School A isn’t as good as School B at getting you to Silicon Valley/a PhD program/med school/whatever doesn’t actually make it so (though it may make you try less hard, but that’s more you than the school; in general, for most career paths, it’s more about you than your school).
Opportunity is opportunity and opportunity/resources are discernable; and they don’t change due to the perceptions of HS students.
