https://en.wikipedia.org/wiki/Pareto_principle https://en.wikipedia.org/wiki/Pareto_principle When you select for the tails of the normal distribution, the following distribution will have a pereto-like-shape. Since it's such a high skill field (abstract symbol manipulation to create automatons that carry out work), it selects on the right end of conscientious & intelligence distributions, which are both normal. That has a long tail, and incomes follow that distribution. The more normal distributions you are cross selecting for, the more extreme the skew becomes. When you begin selecting for intelligence, conscientiousness, privilege of opportunities, sociability, creativeness, negotiation skill ... it gets more and more extreme. Practice :)
