That is really impressive! And look, more schools should focus on this metric.
As an Ivy League grad, you can get the "education" anywhere. Ivies, State Schools (ha, ome Ivies are State Schools!), Community Colleges, Udemy, Khan Academy, YouTube... once you learn how to learn, the sky is the limit. And learning how to learn on your own, and in a way where your failures as you learn aren't life threatening... I'd say that's the real key to life-long success.
But there's nothing going to an Ivy taught me that was unique to that school. For the most part, I found the "famous" professors to be miserable during my undergrad. Like they may know the material inside and out, and their books may be used by other schools, but that doesn't make them good lecturers. In fact, most of them kind of sucked at it, and you could tell it wasn't how they'd spend their time if the university didn't say, "Oh, thanks for the book, keep 'em coming, but you also have to teach an undergrad class too..."
Outside of education though, that's the real benefit. The network there... the opportunities some of my peers had, and I had, because of their connections... And it's a mind shift. Higher expectations, to be sure -- for myself, and others around me. (And, over time, that leads to the ability to teach others ways to improve their game.)
And look, as a kid starting out, getting a few wins in early on makes the world seem a lot less uphill. Even small things, like being able to make a good first impression when I looked for jobs as a new grad (or even 20 years on), people giving me the benefit of the doubt because of the school I went to -- small things turned out to be huge. That initial first impression "I bet this kid is good..." is so valuable. Creates a nice confidence feedback loop too.
All things being equal, I sure am glad I went to an Ivy. I didn't learn anything at school that I couldn't have learned other places. Its was just nice to have that networking opportunity. I look through my friends and I have a huge range of highly successful people in my network. And not all of them went to Ivys, but I will say that having that "starter network" allowed me to connect with other successful people, offer them opportunities, build relationships... like attracts like. And having high expectations seems to attract others with high expectations.
(I fully understand now that my going to an Ivy League school, even as a financial aid recipient, really had more to do with my parents than me. As an 18 year-old kid... what do you know? You're just along for the ride, and taking the ramp my parents set up for me -- I took the opportunities I could, but I didn't realize it until much later how my perceived choices were really because they busted their asses to make sure the I had good options in front of me.)
Anyway, for a kid who grew up on a cattle ranch... going to an Ivy was huge for me. Huge. Like opened all kinds of doors that never would have been accessible to me.
