“Trickle Down Housing” is a False Analogy

We know that increasing the supply of housing decreases rent. (Or at least, it slows the rate at which rents grow.)

This is true even when the homes are new, market-rate, and “luxury,”

Yes, on a neighborhood level this isn’t as simple. But on a regional scale, more supply means lower rents. This is supply and demand.

Despite this, I often hear people compare new market-rate construction to “trickle down economics.” They call it “trickle down housing.”

It’s a clever phrase. But it’s a false analogy.

“Trickle down economics” refers to the idea that cutting taxes for the wealthy will lead to more job creation and investment, and through this the money will “trickle down” to everyone else. In practice, this hasn’t worked. Those with money keep their money.

So when people compare new housing to trickle down economics, they’re relying on that history of failure. The phrase taps into a shared understanding that “trickle down” doesn’t work, and then applies that skepticism to housing policy.

But the two are not the same.

Tax cuts for the wealthy depend on behavior changes at the top that may never happen.

When you build new homes in areas of high demand, even if they’re expensive, some people with the means move into those homes.

That leaves the existing housing for the people who already live there.

Comparing housing supply to trickle down economics is rhetorically sharp but economically wrong.

Beware of the false analogy.
