I don't share that intuition. If I earn more money, I won't necessarily save more. I'll buy better food, better clothes, better everything and live a materially more prosperous life. My savings rate may even go down. Or up. It depends on the specifics. When a tech gets more efficient, it causes people to do more. To shape their surroundings and bend reality more to their will. If you can travel easier, you can realize your travel wishes better.
