In the big numbers being in a rich family, in the right social group/culture and in the right country could influence a lot if you become (or continue to be) rich. And that is not an evenly distributed chance, nor requires very high IQ. Having/seeing the right opportunity in the right moment in the right place, while having the right contacts, may give you a hand up, and again, that is not chance, nor specially being far above average in intelligence. Another non random factor is your "cultural" intelligence (as opposed of genetic one). How you learn, what you learn and at which age (and more factors, like food, family and friends) affects your intelligence or at least some flavor of smartness. And this could be partially attributed to inherited wealth too. And not every activity you get into will give you equal opportunities of becoming rich, starting with a somewhat common baseline. If you apply your big intelligence to theoretical mathematics or quantum physics you may have less chances to become rich than if you apply your average one in the field of finance. And you must again be in the right country/social class to even try that. If you use chance to decide why some people in the right country/social class/education/etc got uber rich and the others just rich, you may have a point. but it is not even for all the world.
