Analogy Fail: Ferraris are mass produced.
Actually, in the modern era, things that are mass-produced are usually of vastly greater complexity than things that aren't, because the scale of manufacture means you can invest a lot of Capital, including engineering design.
So, while there is a difference between "lower quality" and "higher quality" products, production volumes aren't a good indicator; if higher quality goods have a lower volume that's usually a
demand-limit rather than a supply-limit.
