I really dislike when people say things like this. The reason the poor stay poor is because most of the time, they are lazy or not trying and just sit on their ass waiting for something to happen. There are several things you can do to change your state of wealth in this game. For instance, you can WoE for a guild, several guilds pay salary for doing events with them(if your argument to this is something along the lines of "oh i have no gear" or "not geared enough" most guilds take players long as they are active and have an Fset and Cape which you can vote for both now so no excuse). You can use the thana room, it's basically free since all you have to do is hunt the frags for what? An 8k payout or something around there? Not to mention hunting zeny or questing LHZ or legendary weapons which are bought frequently.
Yes, I agree some people overprice items unfairly, but if someone sees this and they want to get that much for the same item they have, are they wrong for this? I don't think so, but the cycle continues and until more items start to flood the server or everyone starts to sell their items, this won't change.
