Sorry for this way late reply. If you have the time watch a video on YouTube called the zeitgeist addendum, explains everything way better then I ever could. But the gist is it's all in the fractional reserve lending policies, the way the banks can lend money that they don't actually possess thereby creating money (more accurately creating debt, since we have a debt based currency), and charging interest in that money that they created. If all the banks called in all their loans, there's simply not enough money on the planet to pay it. Also that debt is in itself a form of power, since they never even had the money to begin with and they have large institutions and governments that can't pay their debts they effectively own said government, or have access to all the collateral of the borrower. That's the reason there's new banks popping up all over the place, because they now have assets everywhere due to foreclosed loans that never truly existed. The banks literally own the whole world, all the people in it, and all the property of it. Too term too big to fail doesn't even begin to explain it. That's why they can gamble their loans, lose, and have all those debts absorbed by the federal government. They either win in their investments, or we lose on their investments, but there is never a loss to the banks.
