The problem in Wall Street is because of government interference. More government regulation is not the answer, but rather less.
Did you hear, the proposed source of the sudden huge increase cost of a barrel of oil was actually Saudi manipulation that worked? They raised the price of a barrel of oil to make money, then they took that money and went to wall street and bought lots of oil stocks ... the price rose on, then sold made a profit, so they bought more stock raised the price of a barrel of oil again, and repeated the whole process, until we had $150+ per barrel.
Now this may be legal ... but there needs to be some way to prevent other governments anti to the U.S. from manipulating our WS system enough to bring down our economy the way it has.
Sorry ... it was on a TV program last week or so. I do not remember the source exactly.
