Yeah ok, I don't have anything to point to which refutes that.
An analysis of the breakdown of the contributors to the Australian housing bubble in 2018 would be cool to see, though. Probably some kind of even split between significant foreign investment in property, negative tax gearing, zoning laws, transport infrastructure issues and a one-off $900 payment that went to middle and low-income earners a decade ago.
Damned trickle-up economics.
