I’m a bit confused about the point that you are trying to make here. As far as I can see there is nothing in this about social class in the traditional meaning of the phrase. It’s about your view that people who study quantitative subjects (rather than poor benighted arts students like me) do better in “business”, make more money, and become more successful.
You’ve cited some examples of people who, it is undeniable, are successful, but who also happen to fit your argument. But equally there are many successful businesspeople who did not study maths/CS/physics (John Paulson, hedge fund manager, started NYU doing film studies) and there are many examples of people with qualifications that you would probably argue show them to be intellectually gifted, who have completely failed in business (the example par excellence here is Long Term Capital Management, stuffed full of PhDs from top schools).
A key in this whole discussion is to define success. If you are just using money to keep score, then consider Tom Cruise, who didn’t attend any university and is worth around half a bill.
