You’re so close! Once you figure out those luxury flats will go for quite a lot, then free up downchannel housing you’ll understand how this all actually shakes out when people can build.
But that’s not what actually happens!! It’s like the Laffer Curve, we don’t actually see any of these benefits of letting the free market try to create all these supposed benefits and efficiencies. The textbooks say they should happen but in practice they never do. Even when the UK government releases state owned brownfield land, developers build overpriced flats no one in the local area can actually afford. So it doesn’t actually create any net new living space because 1) the local populace can’t afford it, 2) it gets bought by investors.
How does having investors scoop up luxury flats release downchannel housing at all? I have never seen that happen. Even in places where land is cheap and zoned for residential, like in areas of Utah, they never actually build affordable housing on it. People end up locked into renting.
The Ladder Curve is not a concrete thing. It’s a metaphor to explain optimal taxation. It was literally first drawn on a napkin
How does an increase in supply that outpaces demand not lower prices? That’s the question you need to answer.
“Locked into renting” and “affordable housing” have no meaning and are useless terms for discussion.
It’s not a metaphor, it’s as you say, an economic theory for the optimal rate of taxation, which exists somewhere between 0% and 100%. However, in the USA it has been put into practice over the past 30 years, where taxes on the extremely wealthy have fallen drastically over that time, with the thinking being that this would raise government revenue and also all that trickle down hogwash. Only it hasn’t, and it has only served to weaken revenues at the local community and state level, and caused wealth inequality worse than the gilded age.
In terms of housing, you are correct in principle, if the supply of housing was to drastically increase such that it outpaced demand, then sure, prices would fall. But this is a specious argument for a number of reasons. First, even if zoning was abolished tomorrow, it’s impossible to actually build new housing in most of the world’s most expensive cities, such as NYC, London, and LA, because there’s simply no space to build anywhere, except on the extreme periphery. London still has some brownfield land, but LA is boxed in by mountains, and Manhattan literally has no more space because it’s an island. So where do you actually build? Vertically, okay, but then you have destroy existing structures.
Secondly, and perhaps more importantly, even if you allowed easy zoning, and cleared out lots for mega towers, who is going to actually build so much supply so as to flood the market in order to crater prices and make housing affordable? That’s the dumbest thing ever, no builder wants to see prices come down, that would be like DeBeers flooding the market with diamonds, massively increasing supply and dropping the price, and killing their own profits/margins. Builders want high prices, not low, they have no incentive go on a building boom like in 2007 such that prices drop.
So you’re left with my original argument: you can’t leave housing solely to the for-profit, private sector. They have no incentive to build affordable housing, or flood the market with over supply in order to drop prices.
