This is what politicians just don’t seem to realise about industry and engineering.
People get good at things by doing them repeatedly and optimising. That’s the only proven way. So of course if we build a couple of naval ships every decade, maybe a giant train line every 30 years or similar, it will be done terribly.
Then there’s lots of hand wringing about how we can’t do this any more.
We are so, so far behind China in industrial capacity now. If we ever did get in a war with them they’d outbuild us 10 to 1. Technical advantages would be pretty much irrelevant at that level.
- pas 2y agoNot just politicians in general, but people, of course, are always surprised how expensive housing is, but then reject any kind of streamlined mass-manufactured option. They are conditioned to worship at the altar of small businesses and good ol' craftsmanship. (And plot after plot they blindly erect yet another replica of the standard American Dream with the compulsory backyard where they truly can be free, and conduct HOA approved activities, and complain about the neighbor making a noise with their fucking weedwhacker, and complain about the other neighbor that has a problem with the smoke from the occasional backyard cooking.) Otherwise it's gentrification, more traffic and oh, ew, maybe even affordable-unit-dwellers.
- ajb 2y agoIt's true that small businesses and craftsmanship are not efficient, but that's not usually the main reason why houses are expensive. They are usually expensive because of planning controls. Look at the price of land: in places where houses are expensive, land with planning permission is by far the largest component of the cost of a house. Building work being expensive is usually a consequence of this. Having said that, I've no idea where you live so it could be completely different in your area
- lotsofpulp 2y agoThe standard tract built house erected in 100 days by DR Horton/Lennar/etc is the streamlined, mass manufactured option. Any more streamline than that is apparently more costly or otherwise unappealing to people. It isn’t not small businesses building most homes in the US, they are large, and sometimes publicly traded businesses.
- bluGill 2y agoEvery once in a while someone will bulid a house in a day. However it is more costly to do this. you either need expensive really fast cure concrete or a low quality wood foundation. You need to carefully plan who is where and when so plumbers and electritions are no standing in the same spot (think sink with an outlet nearby). You need to specify where everything is to a pipe and wire are not in the same place with enough slack that the pipe can be put in. You pay your crews to arrive early so as soon as the last crew is done with a section next con start. your 100 day house has slack built in so if one crew is running late the next isn't affected. This means you can tightly schedule the labor a month in advance.
- lotsofpulp 2y agoTract home builders are building hundreds of homes in quick succession. 1 house in 100 days, but also 500 houses within 2 years. There is no slack, because each team has to be operating in lockstep so work never stops, otherwise margins tank and a profitable project becomes a loss. The expertise of managing and executing this non trivial task is why those businesses succeed, and why landowners outsource development to them.
- bluGill 2y agoThere is slack - but the slack is in the house schedule not the human. A house can sit for several work hours with nothing going on and not care. The humans working on the house do not like being idle - they are working for money and when they have no work they get no pay and in turn that makes it hard for them to pay their own bills. The bank cares a bit about idle time, but the interest charges from a few hours here and there of idle time isn't that much and so that is where builders put the slack in. Of course those interest charges still add up and so there is effort to reduce them but the costs of scheduling a crew and then not being ready for them adds up even more than interest.
- pydry 2y ago>people, of course, are always surprised how expensive housing is, but then reject any kind of streamlined mass-manufactured option. It's a pretty specific type of person who rejects the construction of streamlined social housing - somebody who definitely doesnt pay rent and someone who probably receives it.
- bluGill 2y agoNo it is people who have no idea how mass produced a conventional house is. They think there is something for a factory to do. Then they go elsewhere and complain how houses all look the same these days.
- throwaway173738 2y agoYeah a competent framing crew can bang together a 2-story 4000 square foot home from sticks in 2 weeks.

- bombcar 2y agoTransportation costs are so high that it's often cheaper to stick-build a house than to bring in a manufactured one. The manufactured ones only win when it's very tiny (think: trailer) or when you do an entire development with them, and even then you often need a rail line or something to make it work. Even the "put together on site" kit ones run into problems that the stick-built basically avoid, like things not lining up exactly right. We're building houses, maybe not enough, and almost certainly not exactly where some people want to live, at the price they want. But they're being built.
- bluGill 2y agoNote that stick built most of the wood is cut to size at a factory. If the wall is 8 foot, then you just grad the precut stack of 92-5/8" studs (after adding the top and bottom plates that works out to 8 foot with some needed slop for the ceiling and flooring), likewise you will get 104-5/8" for 9 foot walls. No other wall size is common in the US because then you have to cut all the boards on site for higher costs. Likewise the windows and doors are standard sizes from a factory. No plumber is making pipes on site, they just use a factory made pipe, valve, sink... A modern house really is a kit, there are just enough different size options and styles that there are many factory options and it seems each is custom even though most of the parts are standard.
- throw0101c 2y ago> Not just politicians in general, but people, of course, are always surprised how expensive housing is, but then reject any kind of streamlined mass-manufactured option. You can build a tract of homes in 90 days (or less) using stick frame. They won't be fancy, but they'll be up to code (and with a little extra cost (<10%) and effort, they can be made much more efficient than just code). A crew of 4-5 guys (plus some subs) can build a custon home in 80 days: * https://www.youtube.com/watch?v=LYd73YP57Ik&list=PL8XEQ1XKYNDVZVnHtVW2eUxIF9Tqb4pIc https://www.youtube.com/watch?v=LYd73YP57Ik&list=PL8XEQ1XKYN... If you pipeline that and use a standardized, cookie-cutter plan an entire row can be build out in a similar time frame. Production builders do it all the time: * https://www.newhomesource.com/learn/custom-or-production-builder-right-for-you/ https://www.newhomesource.com/learn/custom-or-production-bui... There are of course mass-manufactured elements that can speed things up, like using trusses. There are also now services for pre-cut framing that saves on-site effor of measuring and such: * https://www.youtube.com/watch?v=o2FdAdxjSpw&list=PLDYh81z-RhxjSuCfjHdlIMWpqhyt5jNPX&index=5 https://www.youtube.com/watch?v=o2FdAdxjSpw&list=PLDYh81z-Rh... The building of the structure is not the bottleneck, it is the approval process and NIMBY road blocks that can add 2(+) years to a project.
- throwaway173738 2y agoIn my experience pre-built framing just moves the error down into the foundation.
- throw0101c 2y ago> In my experience pre-built framing just moves the error down into the foundation. There are ± tolerances at every interface, so if you're off a bit on the foundation, you can balance things out in the rough frame, so by the time you get to finish framing things are pretty square/plumb/level. But if the pre-built stuff is ±0, then there's no wiggle room in that part of the build, so the rest of it has to be that much tighter as you've not nowhere to adjust things.
- wrfrmers 2y agoIt's not just the cost of building the house. Utilities and infrastructure (and the taxes to pay for it all) add up. Now, if you were to build smaller, densely, and close enough to amenities that residents could walk or bike to their daily activities, or to public transit that can take you farther away, you save a significant amount on initial AND recurring costs. And what's better, people WANT that! Or, a least, they're willing to eat the downsides in order to benefit from the upsides, including lower costs. But there lies the rub: when these types of places get built, they get offered at market pricing, not in a way that reflects their lower costs. So people say, "Why spend the same for less?" and move to a traditional suburb (or, more likely, put off home-buying altogether). The problem with housing in America always comes down to the way it was financialized and securitized: too much relies on "line go up, forever". There's no room for new blood/capacity (read:competition), there's no room for "investments" to lose value.

That's a reasonable explanation but it's not exclusive. You can still face these challenges and not do a terrible job. There is plenty of evidence this is the case. > Then there’s lots of hand wringing about how we can’t do this any more. Of course we can. > so far behind China in industrial capacity now. We just don't want to pay first world wages for the work. The arbitrage has been beneficial for a few decades as long as you're not concerned about high quality capacity. Which is what you'd want for a war.
- Yeul 2y agoIn the 1970s the Netherlands tried to save it's shipyards (from Japan and Korea at the time China was nothing). There's just no point to it your oil tankers end up more expensive so nobody will want to buy them.
- bluGill 2y agoThere is the real problem. World demand doesn't need enough oil tankers to support the level of automation needed to be competetive. navy is different in that it is worth building your own and having that automation just in case.
- timewizard 2y ago> In the 1970s the Netherlands tried to save it's shipyards They have several successful ship building companies today. Is your point that it didn't work? That doesn't seem born out by the reality of today. > There's just no point to it your oil tankers end up more expensive so nobody will want to buy them. So the quality is equivalent? And there are no buyers who require high quality in their ships?
- Neonlicht 2y agoThe Netherlands still has very successful shipyards but they focus on government contracts (navy, coastguard, ferries) and (super) yachts. The giant container ships and mammoth tankers are all built in Asia.
- suraci 2y ago> If we ever did get in a war with them is that normal to think like this? do most americans think like this?
- gustavf 2y agoIn an article about naval shipbuilding I would say thats a normal thought.
- relaxing 2y agoDefense planners think like this.
- vuurmot 2y agolooking at this from the other side of the world, it feels like americans are so insecure, as if they are constantly frightened
- plastic3169 2y agoAnd who would ever even attack the US? Massive military spending and they are isolated from all the potential enemies behind two huge oceans. Average american should worry about civil war or maybe nukes. Nothing else will ever reach them.
- antalis 2y agoThey may not attack the US directly like the Japanese did, but China may want to take over its neighbours to expand. Just like Russia could.
- plastic3169 2y agoI appreciate the worry for everyone else. Truly it makes a huge difference in global politics. Like parent I am still surprised how paranoid the US seems. It’s almost like growing up overprotected you become extremely fearful. There is almost no practical cost to US with going into war so the result is that US is constantly fighting and makes it the core focus of the society (along with innovation and more positive sides of US culture) Pearl Harbor was devastating and Hawaiians probably have plenty of reason to worry about the defense going forward. Then again I looked up where it is and I am shocked how remote the islands are. I think it was first and foremost symbolic attack. Not a real threat to west coast.
- potato3732842 2y ago>This is what politicians just don’t seem to realise about industry and engineering. Who gives these idiots power? Oh, that's right, we do. Every two-bit is happy to screech about economics of scale out of one side of their mouth but you turn around and pick some other issue that they feel differently about and they want it regulated in whatever way they fancy, economics and long term feedback loops be damned. The real problem is that western cultural norms (because let's be real here, this isn't just a US problem) don't sufficiently punish and dissuade people from being like this. It's not even lightly taboo unless you're a public figure and do it flagrantly, and even then nobody "cares", it's just an angle by which the people who don't like you get to fling rhetorical poo at you. And the problem runs bottom to top. It's not just the politicians, it's all of us.
- bluGill 2y agoWorse if someone does care, the other side see this and reflexively opposed it. So often good things one side starts are stopped by the other the next election and so progress could not be made.
- nonethewiser 2y agoThe input cost prohibit economies of scale. The US cannot produce ships at scale without drastically lowering labor and material costs. This is a features of deindustrialization, offshoring, specialization, etc. The so-called uncultured rubes decrying globalization have a point on this one.
