Earlier quoted context omitted.
You've won the lottery, but you don't want to acknowledge that you won the lottery. You want to feel they you deserve your position through hard work and talent. You're living in a society where people are credulous, to some degree they believe that hard work and talent are related to success. So what will happen? Everyone you hire ends up patting you on the back, telling you what a great guy you are.
> to some degree they believe that hard work and talent are related to success Does anyone actually believe that hard work and talent are either zero or negatively correlated to success? I don't think the correlation is 1.0, but I firmly believe that it's positive for both.
And therefore when people say [some race] makes no difference in [some behaviour], and other people say "Why is it always [some race] when we see [some behaviour]", and others say "the observation that [some race] leads to [some behaviour] is false because 50% of the time I see [some other race] being worse than [some race] in terms of [some behaviour]" they are all completely right, but just focusing on different properties of the distribution.
So back to your example, yes, in the extremes, many people who are ultrawealthy may have had those behaviours. But by far and large those behaviours don't make much of a difference to the overwhelming majority of the population, and therefore it's likely that other factors were far more important in terms of making an ultrawealthy person becoming ultrawealthy in the first place. At best, someone who was destined to be ultrawealthy didn't make it because they didn't have those behaviours, but that's more like winning the lottery and being too forgetful to go cash it in, rather than having characteristics that will help you win the lottery in the first place.
