Everyone in a declining population country will implement this strategy to keep asset prices afloat. The pool of people you want to immigrate to your country is not large enough to support that strategy.
Soon the government will have to provide huge incentives have children or immigrate. Then the cost to maintain that asset price is larger and more direct.
Is this true though? In Vancouver apartment prices have increased by 600% between 2000 and 2024. And Canada is still taking in between 500k to 1 million immigrants yearly. https://topqualitycanada.ca/2023/05/15/shift-of-two-decades-...
The problem with immigration this way is that there’s a careful balance of cost vs production. The question is already becoming “is this net positive” and will soon become “what deficit are we okay with running to prop up the asset market”
