Definitely, but I think that's because of the lack of tradespeople and the barriers involved in building new houses. It's hard to build multi-unit-dwellings in cities now, so if you ever get an opportunity you're building a luxury megaplex to squeeze the max profit out of it. And sure you can look further out, but then you're looking at school district problems, lack of public transit, lack of amenities like grocery stores, restaurants, theaters, shops, culture centers.

I think a lot of this probably boils down to our insistence that cars be huge parts of our lives? It's really incompatible with the 15-minute city just because of the space requirements (parking at destinations, parking at homes, street width), and let's not forget maintenance costs and noise/pollution externalities. But I guess in the face of no public transit, what are we supposed to do?

I live in flyover country, and good tradespeople have all the work they want. They're turning down jobs that aren't highly profitable/easy.

Definitely, why bust your ass to drive far out of town or build an irritating thing when you don't have to?

I... maybe think the same thing about the tradespeople shortage as I do about the nursing/teaching shortage? We super need them, wages are going up, but supply isn't, which breaks the law of supply and demand (more or less). I think the cause here is a culture one, like there's not a lot of prestige or money in this blue/pink collar kind of work (generally, not always), so people (millennials) went into white collar professions instead, so we have a glut of people with bachelor's degrees and college debt, and a shortage of people with trades credentials. I'm handwaving a lot, but it seems intuitively true to me.

At least where I live, there's no stigma to being a contractor or builder. Most of them make very good money, and while they might not know the difference between Gouda and Gruyere, they're not dumb hicks.

I do think that it's a tough field to keep "staffed up" since it can wear people out pretty quickly, so it needs a constant influx of newcomers.

Oh yeah actually I remember when I was in high school one of my friends' parents were contractors and they'd build their own beautiful house and landscaped it amazingly. Turns out they were also pretty well off. Definitely popped my bubble about construction.

I think you're probably right about attrition, also the work can be hard on people. But also I think I read somewhere there just aren't a lot of people going into the field. Something about parents encouraging their kids to go to college and become white collar professionals instead of blue collar laborers. That rang true to me too.

Consider that a speculative bubble can create excessive demand.

Ireland had a shortage of housing until the GFC, when suddenly they didn't. I'm expecting NZ to discover the same over the next year or so.

I really think it's as simple as banks lending excessively for non-productive purposes.
