Ford isn't simply claiming that knowledge beats cash—he's identifying a peculiar trap that wealth creates: the moment you believe money solves your problems, you stop developing yourself, making you perpetually dependent on *having* money. A surgeon earning six figures who never reads, never learns new techniques, and never builds relationships with colleagues will crumble the instant health problems prevent her from working, whereas a modest librarian who constantly absorbs ideas and builds genuine skills remains unshakeable. The distinction matters because it separates the wealthy from the truly secure, and explains why lottery winners so often spiral into ruin while self-educated people often build enduring lives.
