A monopoly is like running on firm ground. Nothing compels you to move, but if you do, you move forward. The faster you run, the more scenery you see - so you have some incentive to run fast.

Instead of abandoning competition and giving banks protected monopolies once again, the public would be better served by making it easier to close banks when they get into trouble. Instead of making banking boring, let us make it a normal industry, susceptible to destruction in the face of creativity.

Competition is like a treadmill. If you stand still, you get swept off. But when you run, you can never really get ahead of the treadmill and cover new terrain - so you never run faster than the speed that is set.
