Oddly enough Harvard MBA along with Stanford are the only two worth getting in 2022. And that’s only due to school network not the actual education. It’s really the y-combinator effect at a corporate level.
I do agree that there's a heavy power law on program value, but I attribute it more to the scarcity of great professors and the peer learning advantage of highly selective programs.
Your ycombinator analogy still applies pretty well actually.
