I thought Ferengi did that by clanging the bars together and looking for the ding.
Something I would have loved to see in a Ferengi plot is, the Ferengi are going around to non-spacefaring planets in Federation space and selling them modern technology. This could have ended up in Quark-worthy debates.
"How dare you arrogant Federation types decide which cultures get to join your galactic civilization and which don't? We Ferengi are providing an opportunity for billions of people to share the same wealth you possess."
"And profiting off it in the meantime!"
"We make profits, they get to advance centuries in a matter of weeks. Everybody wins!"
Then they could turn that into a real debate over the prime directive and we could see some planets doing well with it and others destroying themselves.
