That is how they get filthy rich Ron..with other peoples money…no skin in the game.,..,all the risk is on the investors who are the U.S. TAXPAYERS and then the investors on the otherside of the coin..they play both sides of the coin…they and their investors insured their risk on the mortgages…we the people were the biggest losers in their game…our pension funds, 401ks and social security money is gone…..they and the corrupt politicians stole it all…along with our jobs and millions of homes…the people who still have jobs are paying for some of the missing money…..but as the economy worsens and more jobs are lost the truth will be revealed…this ponzi scheme is a failure because of traitors from within who allowed the biggest robbery of our wealth in history..the failure of MF GLOBAL proves no one is safe when they can gamble with your money in secret…just like what ENRON did with algarithms and speculation…all smoke and mirrors……if the ceos…..had to match their investor risk…the bets would be a lot less risky..they gamble with other peoples money on anything you can imagine unregulated…
