This is one of those arguments the grand parent was talking about. Unfortunately this argument is why someone has a larger salary than someone else, not why there are disparities between groups. Unless different groups unequally finds themselves being "right person at the right moment", it should statistically average over time. That said, I don't see a good reason to defend salaries that don't match performance. It's sometimes a reality, but still not desirable. Especially since many times being the "right person at the right moment" isn't luck. It's knowing the right people and having that matters more than your performance.
