Not sure I’m understanding this objection. The parameter in question is ability of a society to generate extreme outliers in achievement. In economic $billion net worth is a good proxy, though I’m sure we could look at things like publication citation rank or number of gold medals instead. We would certainly want to scale whatever number by the size of a country since that corresponds to the probability that a given individual in that society can achieve that level of success. Comparing the US to China, for example, in total magnitude will naturally bias to China since it has 4x the population. That means that although both societies have a similar number of billionaires the probability of being a billionaire in the US is ~4x greater.
