Ferengi Rules of Acquisition

[Weltall]

My point is that the show relied so heavily on this idea for almost 40 years that there's a trope named after it. If you see a familiar, recurring alien, you automatically guess what you're in for and you're usually right.

This is why you have a list of Ferengi aphorisms and the list is cartoonishly ultracapitalist. When you stop to think about some of the alien cultures, you have to wonder how they ever developed civilization and a level of spacefaring technology when their very biology seems to lock them into a singular character trait, to which adherence would have no room for anything like science.
