Vulcan: “Do you propose to lecture me on logic?”
Quark: “I don’t want to, but you leave me no choice.”

One of my favorite Star Trek moments. ST never paid much attention to economics, because they’re socialists at heart. Not that that’s a bad thing, per se, but even socialists need to pay attention to the bottom line. Here Quark explains the economics of conflict to a Vulcan in one of the best moments in Trek.
