Fed lowers interest rates, it doesnt work. companies inject foreign currency into the market, again it doesnt work. What happens then? The world turns into a noisy garbage dump. However, suppose that by a miracle, layout has been established. In order not to disrupt this layout, a new reserve currency unit must be determined. This would probably be the euro or sterlin and maybe the yen. Regardless, the country or union that holds the worlds reserve currency will be much more aggressive than it used to be.
