Increases in the scale of production, as we have seen, often bring down certain production prices.

"Diseconomies" resulting from shrinking scales of production, as when the market for handmade pocket books, horse-drawn carriage, grandfather clocks, custom tailoring, and handmade furniture contracts, push up the price of such products not only absolutely, but relatively far above what they were in the old days, when skilled labor was cheaper and more abundant.
