Engineer/technical/science-type people tend to have this belief that wanting to reap the value they create makes them "bad people" or at the very least not a "good engineer/scientist/etc."

Apparently, only business and finance people are allowed to want money because they provide a useful service or just because they want money.

I personally believe that in a capitalistic society, it is imperative that everyone tries their best to extract as much of the value that they create. Otherwise we end up with massive inequality.
