Oh, Chesterton. He wants to argue that seeking "worldly Success" per se is impossible (and impossible by definition, if he can), but ends up arguing mainly that it's immoral.

I hope no one takes his word that the only instinct that makes people rich is greed, or that it's "cheating" to seek to better yourself in any way besides skill at your trade, which we should tell young people will make them rich because at least this advice is noble even if it's "fallacious."
