Monopolies are not so difficult to break. You just need to convince the politicians that doing so will get them reelected. And to do that you need to get the public really annoyed. Now how could you possibly do that I wonder <grin>
More accurately, you convince them not breaking or adequately regulating the monopoly will force them to spend more time with their families after the next election. In the experience of gun owners, this works rather well after you've actually done enough times, e.g. every bi-annual national election from 1994-2000.
