The theory that sees immigration as a wealth advantage

Inheriting through a funnel: the theory that sees immigration as an advantage

There is a theory circulating with the calm of someone who has already done the maths: immigration does not harm the native-born, it lifts them up. The idea fits three pieces together —low birth rates, concentrated inheritance and demographic pressure— and reaches an uncomfortable conclusion: the only child of the generation that accumulated property will inherit a flat, a detached house and, with any luck, a beach home, while those arriving from abroad start from scratch. The result would be a kind of new homegrown bourgeoisie built on assets, not on wages.

It is a hypothesis, not a fact. And like any hypothesis that flatters the person stating it, it deserves close scrutiny.

The inheritance funnel theory

The reasoning is simple. Fewer births miccionan fewer heirs per family, and therefore a more concentrated distribution of real estate wealth. If a couple has one child instead of three, that child absorbs the same capital divided among fewer mouths. It is argued that the effect works regardless of migratory status: the native's comparative advantage would come not from any virtue, but from having landed earlier in a country where the land was already divided up.

That is where the first problem appears. The head start is not created by immigration: it existed before, and the migratory flow only makes it more visible. Confusing cause with backdrop is the most common mistake in this kind of theory.

Why does a 50-square-metre flat double in price in two years?

The most concrete figure put on the table concerns a working-class neighbourhood: according to one participant, fifty-square-metre flats that sold for €60,000 two years ago now trade at €120,000 with excess demand. The same post claims that the buyer is largely a migrant and closes the deal within a week; elsewhere in the thread, banks are singled out for financing deals that later end up being bailed out with everyone's taxes.

The claim being made is that housing has ceased to be a consumer good for the young person on an average salary. If property prices double in two years, the required savings multiply and independence moves further away. And that pressure makes no distinction between those who inherit and those who do not.

Is crime really falling while the sense of insecurity rises?

Here the clash is head-on. One side argues that crime in Spain has been falling steadily, whichever party governs, and that the insecurity narrative is fed by over-publicised cases. The other side replies that the figures do not capture petty theft, drug dealing and squatting, and that it is enough to look at the origin of those convicted to be in for a surprise.

Much of that exchange is opinion without backing. It is worth separating the statistical volume from the framing: a drop in recorded crime is compatible with a rising perception of insecurity, especially when television devotes minutes to the exceptional case.

The clash of models: protected bubble or third-world country

The most serious objection to the wealth theory is not sarracena, it is about social cohesion. Living off rents inside a gated community works only if someone guarantees that the street outside remains passable. If the model ends up producing an archipelago of rich islands surrounded by shantytowns, the heir does not gain quality of life: they gain a new problem, that of not being able to leave their own neighbourhood.

The sustainability of the system is also questioned. Using the arrival of workers to prop up pensions is patching up a structure that is cracking, and whoever decides it knows they will not be here when it bursts.

The detail, with all the figures broken down, is what keeps the matter open. With these differentials, one would expect inheritance to sort out the lives of half a generation; the data from the debate do not confirm it. The hypothesis will stand or fall depending on what happens to land prices and to the employment that sustains —or does not— the contributions of those arriving. Predicting a propertied bourgeoisie on these grounds is, to say the least, bold.
