In Australia we have a housing bubble, but the problem is woven very deep. Our tax system favours property investments. Our top tax rate (45%) kicks in at extremely low levels of income compared to globally ($180,000 AUD which is around $135,000 USD). The system provides all kinds of tax deductions to investment property owners, and ways of making paper losses to offset income tax.
Much of our economic activity is banking, retail and construction. Much of which is fuelled by the churn in property with ever increasing prices. This economic cycle kept Australia out of recession until Covid hit. Now that the average house is over $500,000 AUD, we have large swaths of the younger population leveraged to their eyeballs in debt at a 2% interest rate. If housing prices fall or interest rates rise there will be a collapse, and a good chance of an extended recession we have avoided.
The best case is they slowly the market down, we have a moderate rate of inflation which allows the real value of houses to drop. At the same time reduce the tax benefits to property investment.
Unfortunately this won't happen. The political class knows that the median voter is a home owner, and its in their interests for housing prices to keep rising. They are just hoping that it can keep going until after they are finished. Totally not jaded about not being able to afford a house in my late 30s due to being wiped out in the 2008 GFC and then starting a family.
