Somewhat tangential to the topic, https://personalmba.com/ teaches you more or less all the book knowledge of a fairly decent MBA program, for an infinitesimal price relative to what you'll pay at an Ivy league or even a state school.

What you don't get w/the Personal MBA is the support of your professors, other students, and most importantly the network and recognition ...

MBA is really something one should do if they're passionate about people, relationships - e.g. what any solid business is made of.... more so than about just the knowledge or what school they go to.
