The U.S. Fed is privately owned. Some of the biggest banks in the U.S. have ownership of the U.S. Fed. These banks are heavily involved in the Gold trade and Wall St. They will never allow any regulator to audit their holdings. These banks get fined but its just a shuffling of printed money.
This in my opinion is a significant reason as to why no one in the banks or Wall St ever being charge or tried and no one has or will ever be convicted.
Simply put the U.S. Fed and by proxy the Government is ruled by the Financial Royal Family and the Banks.
