No Scale, All Scandal
Where are the economies of scale in homebuilding?
Even when builders crank out homes, commenters say the savings barely show up
TLDR: The article says even building huge numbers of homes doesn’t slash costs much, because houses have too many messy, location-specific expenses. Commenters turned that into a fight over prefab homes, social stigma, and whether builders should just buy the forests too.
The big reveal in Brian Potter’s essay is almost rude in its simplicity: homebuilding just doesn’t seem to get dramatically cheaper when you build more of it. America starts more than a million homes a year, yet the promised bargain-bin magic of mass production still refuses to arrive. The article’s argument is that houses are not like phones or canned food. By the time you add up land, labor, permits, and all the site-specific chaos, there just isn’t a giant pile of easy savings waiting to be unlocked.
But the real action is in the comments, where readers instantly turned this into a miniature housing culture war. One person brought the ground-level reality check: even factory-made homes nearby are only maybe $100,000 cheaper, which sounds huge until your total bill is already $300,000 to $750,000 and everyone collectively sighs. Others went full armchair tycoon, asking why builders don’t just own the forests, steel mills, and cement plants too. Another commenter delivered the spiciest social critique of the thread, arguing that Americans have basically trashed the reputation of factory-built housing by turning it into a class insult.
And yes, the future-gazing got weird in the best way: 3-D printed concrete houses entered the chat, followed by predictable worries about broken pipes trapped inside walls. The vibe was equal parts skepticism, frustration, and meme-worthy "why is housing still this expensive?" panic. In other words: the math is gloomy, but the comments are on fire.
Key Points
- •The article argues that construction productivity has historically improved much less than manufacturing productivity, while construction costs rarely decline.
- •It examines economies of scale as a possible route to lower costs and says these effects are modest in construction.
- •US housing is presented as a high-volume construction segment, with more than 1.3 million housing starts in the prior year, including 942,000 single-family homes.
- •The article contrasts homebuilding with low-volume project types such as skyscrapers, semiconductor fabs, urban subways, and airports.
- •Its main explanation is that conventional US homebuilding already has a relatively small gap between raw input costs and final production costs, limiting the savings scale can unlock.
