How I see it:
1. It's just a game. Who cares if people hack, time travel, buy tickets online (eBay, Etsy, etc).
2. Villagers who are popular are going to sell for than an average villager. This is called supply and demand, as I stated in the Raymond thread. Price gouging isn't fair, yes, but no one says that you have to give them your money.
3. I don't think the mods need to crack down on anyone. How people play their game is their business, even if we may not agree with it. The Bell Tree has nothing to do with how people play Animal Crossing as a whole.
4. People who play the game how they choose doesn't make them cheaters just because it's not the traditional way of playing it.
5. Be patient. Getting villagers you want takes time. If you can't find reasonable prices online, just island hop for a while.
6. I don't if the wage gap and segregation are the right terms to use in the issues around pricing in an Animal Crossing game. I mean, come on- this game was originally for children anyway. Why are grown adults having hissy fits about over the fact they can't have the cat they want? This comment is directed at no one specific, just the issue's attitude as a whole.
7. To reiterate: it's just a game.
