Should the saying go "Too Big To Succeed"

I was listening to a horror story on the radio about a family who was foreclosed on by a large bank due to problem with the paper work. By the time the mistakes where discovered the house was horribly damaged due to winter in a unheated home. It seems that we've all been frustrated by dealing with a large companies and it takes 5 or 6 phone calls to resolve a problems not because customer service people are unhelpful bu because they cannot navigate the maze that is the complexities of the company. I keep hearing the phrase "Too Big To Fail", but in many ways it rather seems that they are "To Big To Succeed". When I was in college we learn't about the economies of scale, but we also learned that after a period growth when an organization becomes too big those economies diminish and become negative. From a profit perspective these companies are great, they make more money each year. I'd rather not do business with these huge companies but you often have no choice because consolidation has left so few players in a particular industry that no true free market exists. It seems to me that these companies are succeeding because there is no true free market because there are too few players in the market sector. As a customer I feel like an ant stuck on a huge super tanker in an ocean unable to turn quickly and a large storm is approaching of change. I don't know if I will make it or even the ship will through the storm.
