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

Actually, yes being rich is not because you are smart person or skillful person sometimes it is by chance, by faith or by opportunities that comes to us. What is the essence of being top student in your class, or have lots of rewards and certificate of appreciation if you don't have any opportunities to grab? That's useless.
