I was part of the banking system for many years - it is unbelievably greedy. There is no respect for individuals, other than how much money they can make. Concepts like loyalty and service have no meaning.
I was not denying that the banking system is greedy, I am saying that it is not more greedy than certain other branches.
I have been part of the banking system for quite a few years as well, and although there is some truth in what you are saying, I have experienced the same things elsewhere as well. For instance in certain IT consultancy firms.
