US Mint - US government owned. The current director has a GE background. Probably no bank ties since his record indicates healthcare versus GE capital. Seems okay.
US Treasurey - US government owned. The current secretary is a former CEO of a NY Bank. (Fox in the hen house)
Federal Reserve - Not US government owned. Run by a group of individuals (aka board). If you look at the board there are some who can be said to represent wallstreet. (Fox in the hen house)
So you wonder why shit happens? It happens because the corporation owns the government.
