Cambridge/Harvard/Oxford/Yale graduates earn 6 figures guaranteed, but I don't know any super rich graduates. This friend of my dad's was a rugby player in his 20s and then went on to become a landlord using extortion and the threat of eviction within the law to cut costs. He is now worth over £5000000 ($10000000), still in his 40s and has only been in prison once for breaking someone's collar bone. Most super-rich entrepeneurs just went to a standard business school and aren't really spectacularly rich compared to Harvard business school graduates even though supposedly Harvard graduates have more cash to begin with.
