Athens is better than Sparta for a few reasons. 1. Athens did not kill babies just because they looked "weak". Who is to say that they are nothing and that they don't have potential to become the next leader of Athens. It sounds to me like the Spartans where like the nazis who wanted a pure race,not so great. 2. Athens cared more about education. Where there any Spartans who bothered to write their history down...NO! It was Plutarch who did, and he wasn't even a Spartan! He was a greek historian. And they actually knew how to read and write, as opposed to the Spartans who taught their citizens P.E., stealing, and killing techniques. Ideas are better than armies, knowledge is power!
My third reason is because Athens actually attempted to have an open market like the ones we have in the U.S. today! Look, Spartans told their citizens that they weren't allowed to trade! Talk about terrible economic growth, and isolationism!
