that gold likely isn't there. that shit gets leased out to banks (who run the fed) who sell it on the open market to drive the price of gold down and prop up the dollar. Then the banks invest the cash with the intent of buying the gold back later when the lease is called upon, but that rarely happens. if the fed ever wanted it back the bank that it was leased to would probably have to buy it back, slightly driving up prices. consequently, this is also why there hasn't been an audit on the gold holdings for like 70 years now they are making interest on other people's savings all the while charging them a storage fee.
