This is a quick video by Bill Moyers. Typically I don't not agree with him, but this is quite good and I have only a few minor quibbles. He identifies the "users" who now run our country and points out it is unlikely we can fix this from within.
The system he describes is one where the government has too much power and big business buys access to this power. This is called Crony Capitalism and is a perversion of Capitalism. Some want to rail against Capitalism as the culprit, but true Capitalism is not the problem, Crony Capitalism is.
