It's a very complex topic, which sadly I don't have time to delve deeply into at the moment. My intent with the previous comment was only to point out a fairly large flaw in the "tax the rich" argument as previously implemented, not to suggest that the actual ultra-wealthy shouldn't pay more than they are currently. In theory there are steps that could be taken to fix the massively broken housing market in most of the Western world. Unfortunately the vested interests and massive financial house of cards built on top of property prices make these steps politically impossible. Therefore, what can't continue forever (unsustainable house prices) will not continue forever, but it will end messily & at some unpredictable future time.
