Your instinct may be to think that whether bankers behave in an ethical manner because they believe that it is the right thing to do or just because they feel forced to do so is neither here nor there. The end result is, after all, the same. But that is far too simplistic; the end result is not the same.
On the one hand, we have bankers who believe in values such as honesty and solidarity. They will always behave in an ethical way, even if given the chance to behave unethically without being caught out.
