Isn't this also how organic food got so much cheaper? In the 90s and early 2000s, nobody was too interested in organic food and the prices were significantly higher than "normal" foods. But as demand for organic foods increased, producers figured out how do organic more efficiently (either because of economies of scale and/or because of tech) and the result is that a jug of organic milk doesn't actually cost that much more than a jug of non-organic milk.
