When I see this quote, I know to disregard the author:

"I have never met one of them who cared about the people they serve."

This is a hallmark of a person who is not able or willing to see the good in others. Sadly, such folks are rarely able to see the bad in themselves, and are infrequently worth listening to.

I worked for the U.S. government in a number of roles over a number of years, and I knew and observed a large number of folks who were very passionate about serving their customers. Many of them were willing to quite literally die for the people they served, as was I when I served as a soldier. I judge this to be ill-informed stereotyping.
