That's exactly what I was looking for.

Mamet's point holds true to this day. Take any high-pressure sales role. Your employer doesn't care how much benefit you've added to peoples lives, they care about the numbers. Customer satisfaction isn't indicative of a job well done in sales, quantity is. Whilst this concept seems blatantly immoral, it's reality.

Swombats post was aimed at start-ups and his point that someone selling on behalf of a start-up should truly believe in their product is spot on however, in the big, bad corporate world it becomes irrelevant.
