While there are a lot of good things that AC teaches you, there is however a secret bad thing that it also teaches you and it just bugs me.
As long as you're the Mayor, yes you have power over what your town looks like and that's cool. But you also have power over WHO stays and goes (which is certainly something a real life governor won't do), plus the capability to trash-talk your residents and any outside visitors (i.e. Mayors in other towns). Basically, yes, it rewards you for being a contributing person thanks to Phineas's badges, but it doesn't penalize you if you decide to be a jerk to everyone, which is something a surprising minority of players do.
Considering the odd scammer and how stubborn certain traders could be in different parts of the web, I have a feeling I'm not alone in this... ._.
