I would suggest that the increased throughput comes from the technological advance. We're getting ever more efficient at converting energy and raw materials into stuff we want. That means it's cheaper. That means we do it more. And yeah, "the economy" includes services as well as goods. But services are performed by humans, and humans need to eat and live in houses and wear clothes etc.
