Once again, how many of PG's essays have you read? This is like asking someone in your English literature class to show you an example of Shakespeare making a joke in one of his plays.
But ok, I'll play along. In the subject essay, PG describes himself as a "manufacturer of economic inequality". How is he manufacturing it? By teaching people how to get rich by creating wealth: "Not just by helping the 2400 founders YC has funded. I've also written essays encouraging people to increase economic inequality and giving them detailed instructions showing how."
So PG obviously is arguing that allowing people to get rich by creating wealth will increase economic inequality. How? By amplifying the variation in productivity between people. And there's no way to get rid of that without getting rid of wealth creation: "Variation in productivity is far from the only source of economic inequality, but it is the irreducible core of it, in the sense that you'll have that left when you eliminate all other sources."
As for the part where wealth creation is what fuels economic growth, do you really need a quote for that? I would have thought it was blindingly obvious. (In fact, I would say wealth creation is economic growth.)
> I doubt Steve Jobs would have created more wealth if he were allowed to pay 10% lower taxes.
I doubt Steve Jobs would have bothered to create much wealth at all if he hadn't thought he could get rich from it. Which is much more to the point.
