The most people are born in September, but the general population doesn't have a ratio of 40/300 born in September. It's a telling statistical characteristic of the billionaire group. Also, the 'dropout' thing is misleading. Steve Jobs and Bill Gates were from highly educated and wealthy families, and both were destined to attend high-tier colleges, but dropped out when they saw the fortune to be made. It wasn't like they were just clueless and unable to attend college for grades or money. A far greater opportunity pulled them aside. Their parents and schools hooked them up with thousands of hours of computer time, which was prohibitively expensive in those days. But their parents and they saw that it was an inevitable wave of the future, so they bought their kids computer time. Not that 'any idiot' could do the same, but it's not that they were exceptional that made them exceptionally successful. It's the exceptions that were made for them. If their parents had sponsored a dozen other kids to get 10,000 hours of computer time, those dozen people would probably be wealthy today.
