So if not everyone, then at least the majority of all people worldwide who work very hard will be successful. I think reality shows this not to be true, hundreds of millions of very hard workers who even exhaust their bodies towards an early and broken death would probably disagree. You are already lucky by birth. Even apart from one's own family, we are placed into environments consisting of culture, institutions and tools developed over millennia. How much the place of one's family within one's own society plays a part depends, some countries are better at letting people from all kinds of families develop, in many others there is a large inheritance factor within families, where family income has a high correlation with one's own lifetime income.
