MIT-Trained Entrepreneurs Create Businesses With $2 Trillion a Year in Sales

I couldn't find a list of companies in the latest report, but I would take it with a grain of salt.
This reminds me of one thread some time ago here on HN about universities claiming numbers of Nobel Prizes awarded to people affiliated with them [1].
This "$2 Trillion" statistics has the same problem - one person can have affiliations with many universities (BSc, MSc, PhD, postdoc, faculty, all can be at a different place). Additionally, a company can have founders from more than one university.
I went to a top Brazilian university. I don't have any hard data but I'm sure the number of companies founded by my university's alumni is much lower than MIT's.
MIT's level might have smarter people than a top Brazilian university but I don't think that alone explains it. I live in Japan now. Most Tokyo University graduates aren't interested in joining startups, let alone founding one.
