I mean, over a career, that’s practically trivial. The $300-500k you pay in tuition can quickly be recouped when your starting salary is in the $200-400k range and only goes up from there. You’ll be doing far better as a Harvard grad than a trade school apprentice. And if you’re an aspiring SCOTUS judge or Fortune 500 CEO, there’s few places that offer you better prospects. After that, the sky’s the limit. 1000% ROI is conservative.
But just getting into Harvard requires a certain exceptional resume and social standing. Bush getting into Yale and Kennedy getting into Harvard are less the exception than the rule. The MBA is just the way you signal to people not immediately familiar with you that you’re “in the club”.
But if you run off and spit in the face of American Imperialism, clearly someone at the Harvard admissions board made a mistake.
