Well, unfortunately they're right. House prices, thanks to consecutive governments have been allowed to become a central pillar of our economy. If we allow that enormous private debt bruden to become unstable, by a drastic cut to house prices say, then we'll start resembling the third rate economy Keating warned about pretty bloody quickly.
I still don't agree that its only a supply issue, the demand levers are stacked to ratchet prices one way that is a key contributor to the soaring prices. We ignore the demand side, we ignore half the problems in the housing system.
On the supply side, if they're really interested in fixing supply the government are gona have to look at a more directive approach to the market. Maybe Chalmers should lend O'Neil his copy of Mission Economy by Mariana Mazzacato.
