I don’t consider housing depreciation (or depreciation of anything excessively inflated) to be a “problem” as much as a necessary thing and an opportunity.
And G-d forbid that our government would be forced to spend wisely. We’ll eventually have to realize that having our military all over the world, and that keeping slightly less than one per cent of our population in prison are unsustainable things. The sooner we do, the better for us.
