Ooooo. Calculus. People like me took that in high school. And BTW, for my BS I was required to take four useless semesters of German.

What you don't know is that every large organization has a class of people who do the heavy duty thinking and design the systems and processes that make the organization far more efficient than local centers of activity could make it.
That way only a few need to have the higher degrees ~ others, like you, who imagined that 4 semesters of German was wasted get to deliver the mail. Plenty of guys on the street have degrees comparable to yours.
