There is ONLY human greed.
This is NOT a system problem, it is a human control problem ... just like our founding fathers told us would happen if we failed to keep our government under wraps and within the boundaries as set forth in their writings and fundamental documents of our origin as a nation.
Power corrupts the human soul and mind.
We ALL know that.
THAT is exactly why our elected "leaders" are to be CHANGED at regular intervals to make sure that those we elect do not succumb to the corruption by being in power too long.
