> As someone who attended an Ivy/Ivy Adjacent, I highly disagree, at least in Eng (and Eng adjacent roles like PM/EM/Sales/Entrepreneaurship and even VC to a certain extent)
In my long but undistinguished career, I don't see that my Berkeley undergrad classmates and I have set the world on fire and we're not powerbrokers by a very long shot. We were all (at that time) from the same chunks of middle-class Northern and Southern California with almost no out-of-staters. Many of us including myself commuted and there was almost none of the stereotypical college social life due to courseload and research (a very big emphasis).
Now, I am sure things have changed in the nearly 40 years since I graduated. Perhaps the increasing cost and explosion of Silicon Valley/CS has changed who came after, where they come from, and their family backgrounds.
> CS/Eng is much more driven by defense and private sector funding, which is biased towards National Labs, which are overwhelmingly managed by public universities.
That used to be true when UC ran LBL, Livermore, and Los Alamos but these days they are run (poorly) by "public/private" consortia. Stanford runs SLAC, Chicago for the moment runs Fermilab - both are private schools. I don't think wealthy families send their kids to any of these private schools with a view to jobs at LocMart, Boeing, or Argonne.
> Middle management turned upper management in most tech companies tended to attend flagship publics in the West Coast/TX/Midwest plus some elite privates like Stanford/Claremont Colleges/USC/CMU, which impacts recruiting as well.
The real surprise here is USC which was a scorned backwater when I was in college. "University of Second Choice" took great strides in the 1990s under Steven Sample. IMO it is far from an elite[0] place like Caltech, Berkeley, Stanford, etc. but the USC network is a Very Big Deal at least in So Cal. At my company, their alumni association virtually guarantees that an applicant will get a face-to-face with a decisionmaking alum while others are getting screened out by the AI or HR.
Edit:
[0] I mean elite in terms of academic quality vs. job/networking opportunities.
