Yeah, it's such a bitter, and wrong, take, it seems like a caricature.
I simply don't understand the "why is it all about money" take, at all. The author isn't saying he wants to but a Rolls and lots of gold chains. He simply want to make enough to be able to be independent (which he succeeded), and to indulge in relatively minor enjoyments, like travel.
"Why is it all about money?" Because some of us like both independence and not starving.
