The point is that the range of human achievement is graduated, and even if we are all given equal abilities and have equal drives, we will not all see equal success. This is a dangerous fallacy. It's obvious when you look at people and conclude from, say, physical stature, that a person is exceedingly unlikely to succeed as a professional linebacker. But somehow we do not even allow for the possibility of our cognitive limits being set by a combination of our genes and our experiences.
