Look at voting rights: we had a security company where 20% more people voted than there were shares. Think you could direct corporate, even national power that way? Without records of transfer, how do you know you own it? Morgan transferred a stock to Schwab but forgot to clear it. Doesn't that mean it's listed in both Morgan and Schwab? In fact, didn't you just double-count and double-value that share? Suppose you fail to clear just a few each day. Before long, compounding the double ownership leads to pension funds owning 2% fake shares, then 5%, then 10%, until stock market and the national value itself becomes unreal. And how would you unwind it?
Work backwards to 1999 where the original drop happened? Remove 10% of CALPERs or Chicago's already devastated pension money? How about the GDP and national assets that 10% represents? Do you tell Sachs they now need to raise $100B more in capital reserves because they didn't have the assets they thought they have? Think I'm exaggerating? There have been several companies who tired of these games and took themselves back private, buying up every share…only to find their stock trading briskly the next morning. When that can happen without even a comment, you know fraud knows no bounds, a story Financial Sense called "The Crime of the Century." No one blinked.
