The Federal Bureau of Corporate Security

There was a newspaper article recently exposing the FBI's fleet of covert, privately-contracted, surveillance aircraft.  It occurred to me that these planes are not searching for terrorists.  They are providing security for privately-owned corporations at the cost of the taxpayer.  It is easy to justify this malfeasance with terrorists lurking around every corner.  Lobbyists pay politicians.  Politicians provide free security through the Federal Bureau of Investigation under the ruse of the prevention of terror.  Who are they watching?  It looks like big business to me.  Feels a bit like Socialism, the government running the businesses the way the businesses want.  Most certainly we do not have a publicly-owned means of production.  Who is shit out of luck in this scenario?  A bit of a conspiracy that seems really possible.
