I disagree with the notion that nature is fair and I present my evidence in the form of any children's hospital anywhere on Earth. Many are born having lost the grizzly genetic lottery into bodies or minds that are genetically unsound in ways which will hobble their ability to progress the whole of their life. And even of those who aren't, many are born into poverty or socio-political circumstances in which they absolutely do not have the same equal opportunities to succeed. Many have to work twice as hard for half the progress, and they may be the lucky ones compared to some other.

Say what you will about Gates, his economics and political leanings, but he was right about this one.
