Three distinct factors are at work here...

...a shared culture that values the privacy of one’s own home

...the planning regimes in all six anglophone countries are united in facilitating objections to individual applications

...Anglophone planning frameworks give huge weight to environmental conservation, yet the preference for low-density developments fuels car-dependent sprawl and eats up more of that cherished green and pleasant land.

The author's conclusion:

Ultimately, whether the goal is tackling the housing crisis, protecting the environme or boosting productivity, the answer to so many woes in the English-speaking world is to unburden ourselves of our anti-apartment exceptionalism.

One reason is that people want houses and it's not sustainable. Large cities need to go up and living in apartment in a high rise should be a norm.

The problem in the word itself even - housing.

It's not that they can't build housing. It's that housing is bought up by private equity and Monopoly prices are set by the algorithm. There are no many vacant homes and apartments being kept vacant to drive up the cost.

Saying 'we need to build more houses and deregulation is the key' only serves the oligarchy

I've went down the YouTube rabbit hole on this.

My favorites have been dirt-inspired builds utilizing technology found in the animal Kingdom beyond humans. Termites are often cited.

Buildings that have natural AC regardless of the season and mostly passively. Ventilation structure that encourages heat sink/release.

And many are made of just dirt, which seems pretty smart. Enormous insulation values. Endless supply.

Same reason we can't build high speed rail, have to get approval by every property owner rich enough to hire a lawyer to build anything here.

A median house price and median salary should also be calculated, those datas aren't very useful without understanding the economic condition of the people

This completely and utterly ignores the capitalist pressures that also hit building materials. Just look at wood prices in the US. Prices have skyrocketed outside of the housing supply as well.

TL;DR: Capitalism is cancer on anything required to live, including the vast supply chain for such goods.

I’d blame Friedrich Hayek, Milton Friedman and their disciples on both sides of the Atlantic. Not sure if a legal system based on Roman civil law/the Napoleonic code would have slowed neoliberalism or whether it’s merely correlated with the cultural divide between the former British Empire and continental Europe.

Also, isn’t Singapore a common law jurisdiction with a solid state-backed programme of building housing?

Or... These are very different places with different constraints.

For example, the US is comprised of 50 states - construction has to meet federal, state, county, municipality codes, and then any federal or state agencies that have a say on construction possibly affecting water ways, natural habitat, etc.

The bureaucratic process is staggering.

And municipalities change their minds every day the wind blows (and who is paying them off).

So it's a problem of bureaucracy and graft.
