Does the Word "Unsustainable" Apply Here?

I found this in the New York Times over the weekend. Yes, yes, I know I'm always a couple of days behind. Deal with it.

Another good word is "bubble."

If that's too small (and it probably is), there's a larger, eye-friendly version of the same graph here.

But, but, the market knows all! Invisible hand! I suppose, when the inevitable crash occurs, the market-knows-best types will simply say that it is a "correction," and ignore the hordes of people who are absolutely ruined.

Sometimes, I wish I were religious like that.
