With the news of Goldman Sachs resignation letter; should we self-assess the way we provide our client's a service??

We, as project managers, also provide a service to our client's. I remember when I first started out in this profession, it was all about ensuring stakeholders where provided with the best service and I forged relationships with client's which, in some cases, have lasted until today (over 15 years).

Is this true of today's profession? how many of us perform their duties not solely for the client; but also to gain a little something for ourselves? would any of us 'go the extra mile' to exceed expectations?

I am NOT (far from it) questioning the integrity of individuals or of the profession, I am merely asking whether, in light of the recent news, we should go through a self-assessment and re-visit the reasons why we do the things we do within the profession.
