The FED is betting it can keep all the foreign dollars off the US market. That's the key that foreign governments are not willing to turn so they devalue their own currencies.
We'll have to wait and see what happens.
We can bet a few things.
Governments will do everything they can to keep the status quo going. Law after law, bailout after bailout, regulation after regulation. Buying gold and silver is a bet that the free market FINALLY in the end does something that the government can't regulate and bail itself out of.
