You know, we tend to disagree with that. Everyone we have ever personally known in finance houses like Goldman (never knew anyone in Goldman directly) have had impeccable moral compasses. They woke up each and every morning to do the best job they could to provide credit, or figure out a profitable strategy for their company, what-have-you. Goldman and the others are not evil (although Blankfein has made some borderline satanic references), what makes them appear less than credible is the instrument that underwrites their entire business.
How can you create a solid business built on the foundation of a baseless trust?
If you take these same types of infrastructures and build them upon the foundation of a publicly accountable ledger, I assure you they will operate flawlessly and the perception of their purpose will change dramatically. This will take 50 to 100 years but it can happen.
Good luck running a financial institution when today you had to search around for the word "patience" in order to gauge your VAR. This kind of foolishness is not how mankind should operate its money supply.
