I read that earlier today. I did not want to post it.
The point with this and other articles, people are making arguments which I think are rationale. Whether they are correct or not, time will tell. It is a bit better than: 100,000 immigrants, people don't care about investments that don't make money because the "guaranteed" appreciation will more than offset. Locals can't afford the market but so what.
I disagree with his Keysian approach of just float more money into the system. That is just distorting all fundamentals and at some point, you have to pay the piper. So while I accept QE1 and begrugingly perhaps QE2, there needs to be an exit strategy because we just go further down the road to oblivian if nothing changes. And hoping that a solution will pop up is questionable.
Interestingly, what do we do in our household Ka1. As you pointed out, we tighten our belts, spend less, don't get luxuries. It is painful but it has to happen. We have to makeup for years of excess. As we all know, nothing goes up forever.
