Why can they manipulate silver forever?
A failed delivery to an industrial user could cause a panic. Industrial users must have real silver, not paper silver, or they will shut down production, which would cause them to go bankrupt. Therefore, once industrial users cannot get silver easily, they may begin to stock up on silver. This could cause further panic for real silver, driving up prices. All price suppressions fail, because they encourage excess demand at the price that is too low. However, silver is an investment, and as such, it has a price curve that is reversed. As silver prices moved ever lower, investors were repulsed by silver. Today, as silver prices move higher, silver investors are attracted to silver. This is why paper money will fail, too. Because they can’t manipulate silver forever.
