History is a flat circle.
My last company was chock-full of Ivy league/Stanford/Berkeley/etc graduates with almost none being the type who actually is interested in technology. About half openly admitted to being a SWE because they couldn't get a product manager role and hoped to pivot into it from SWE after a few years. I will also say that parental pressure had a big part. Why spend 10 years of your life to be a doctor when you can make more money in big tech?
It also became fashionable for people to pivot out of high-finance or management consulting (traditional white-shoe industries) and into corporate development roles at hot companies.
