I am not entirely surprised by this at all actually, anecdotally I have always felt people who achieved success where mainly in the right place right time. Whether that be born to a certain family or class, or to a certain country, or area of a country, these things all effect where we will end up. Good to know us average folk can still make it in this rigged world

Our success is determined by several factors that affects the quality of living that we have. Some are acquired, some are inherited, and some are from chance, but all of these still needs hardwork and intelligence. We can not achieved our goals if we sleep half of our life doing nothing at all. Given the fact, that we got lucky and become rich from chance, we might loose it all, if we do not have the right attitude and failed to become a responsible person.
