correction or disaster, page-3

im getting sick and tired of hearing about this 3 or 4 trillion dollars sitting on the sidelines waiting for a new home. like its a bunch of cash someone's left on a train station seat. this money already has a home and probably only a small percentage of it will ever go back to the market when the time is right.
i remember reading ( & i may be wrong ) that the total of all US stocks listed equals about $8 trillion and about 20% ( $1.6 trillion ) is in the Dow. So given the Dow is about 30% of its high its lost about $600 billion in market caps and in total of for all US stocks ( best guess ) about $3 trillion lost in market caps. So are they saying no one lost any money when taking money out of the stock market and put it on the so called sidelines AND no one has lost any personal wealth over the past few years. Or was the money already out of the market b4 the crash and therefore why do we assume that it will come back into the market.
As far as I'm concerned, its a broker's fallacy to comfort investors. Correct me if im wrong.
