Shalom Chaim,
How can we move control of the U.S. economy out of the hands of a handful of uber-powerful robber-baron speculators and hedge-fund managers? The simple fact is that the fundamentals of supply and demand mean quite little in today's stock market; by mutual agreement, investors can set the price of anything to be whatever they want.
For a couple of examples, consider that real fuel consumption now is barely less than it was last summer when oil cost $150/barrel, but oil is less than half as expensive now (though it is still way too high). Or, remember the big spike in agricultural prices--all because the speculators predicted that someday increasing ethanol production would eat into the amount of available arable land for food cultivation--something that still is not even close to happening.
Finally, it is a myth that the speculators "lose" when real supply/demand do not bear out their price predictions: on fundamentals such as food and fuel, which by their nature are almost impossible to cut back on, consumers are forced to pay the higher prices, so their speculations on essential commodities are always borne out. It's like casino management vs. individual gamblers: the house always wins, because it controls all aspects of the system.
