Flashback to March 2009

Here is a video segment taken from March 2009 after an awful jobs report was released.  The title of the video is "US Economy on the Verge of Total Collapse":   http://track-cell-phones.com/us-economy-on-the-verge-of-total-collapse-cnn/   Notice the panic, the desperation and the hopelessness in this video clip.  This was the day of the bottom.  In hindsight, this was the very best day to buy stocks since perhaps the previous major market bottom in 1982.    What can we learn from this?   Today, the exact opposite situation is occurring.  Surely the contrarian investor philosophy of selling and selling short instead of buying is correct.
