I think your parents socioeconomic class has a big influence on your likelihood to be 'successful' (http://www.economist.com/news/united-states/21595437-america-no-less-socially-mobile-it-was-generation-ago-mobility-measured http://www.economist.com/news/united-states/21595437-america...). Social/networking should also play a big role. My anecdotal observation is, having both of the above (from upper class family and good at networking) is the biggest determinant of success. It sort of makes sense, the upper class bit gives you access to other successful/wealthy people (through private school, parents network), and the social skills the ability to leverage this access. Also, having loads of money from family makes it very easy to succeed. In the UK you'd just buy as much real estate as possible, farm off the management to an agency, and just sit on your arse while the assets gain in value.
