Are Consulting Firms Compromising Their Integrity?

A reader of my website recently posed the following question: "Do you think many professional firms are compromising their integrity in favor of money? The more competitive their environment and the larger their firm, it seems the pressure to maintain or increase revenue is just too great. Are professionals in such firms just high-paid technicians if the driving force from the firm is to make money, even if this means risking reputation? In a post-Enron professional world, what is your take on this? Please be brutally honest."

While I believe in being honest at all times, being brutally honest has gotten me into a lot of hot water, so I'll try to be respectfully and delicately honest.
