I attended a talk by Michael Lewis a little over a year ago. One of the questions I asked him was whether or not he believed financial journalists dropped the ball with reporting on the bubble that led up to the crisis.
Lewis made the point that many journalists had in fact written stories about the real estate excess but those stories were simply ignored.
In addition, if you read The Greatest Trade, you will see that while Burry was pretty early, he was by no means the first to call the trade.
One company I own shares in, chose to publicly detail a very similar CDS trade in their 2006 letter to shareholders. This was before CDS prices skyrocketed and left any investor with ample opportunity to protect themselves from the fall out. At the time, it only cost $1 to $1.5M to buy $100M of protection on banks such as Lehman Brothers or Bear Stearns defaulting.
Most people just choose to ignore the possibility of a bubble bursting. They think the music will keep playing. I remember when I was buying shares in the above mentioned company back in the summer of 2007, when we started seeing subprime's true problems via the troubles at New Century Financial and others. Most commentators and analysts stupidly believed that the problems would not spread beyond subprime mortgage borrowers. But if you had looked at the data, you would have seen that as a result of the leverage employed, by multiple parties, things were much more intertwined.
