Earlier quoted context omitted.
This mindset is tiresome, especially seeing it on Hacker News... I literally went to the cheapest state school in rural Pennsylvania and still was accepted into YC. My co-founder didn't even finish college, at some point I think people just want to make excuses. Also — I don't understand your second point. It's an accelerator. Capital is part and parcel when it comes to accelerating.
Fancy schools are just a way to get pre-vetted candidates. If you aren’t pre-vetted, it doesn’t mean you’re worse, it just means vetting you is more work and has more risk.
For example, wealthy family safety net for extended risk-taking, connections for finding customers and partners and investors, confidence of founders in asserting will over hires, and appealing to class-based beliefs of other investors.
But since most of us aren't investors, this isn't to say that fancy schools vet for, say, hires.
While I generally like and respect the people I've known who happened to attend fancy schools, I've learned not to pay much attention to what schools someone attended.
