I don't necessarily think PG is all about making money. In fact in a recent London talk (http://dl.getdropbox.com/u/142733/Audio/Lectures/future_of_w...), he talks more about hackers' freedom. Hackers are animals shackled in corporate zoos, and they need to be freed to express/invent! He also goes on to say, you can even pay them less, as long you provide them the freedom to release their energy!
PG's mantra is a super powerful one: Make something people want, which also translates to 'Create something, make money while making something you love and your customers love'! That's empowering...
