Why is the North American community so much worse than the Japanese one?

Again, the option is called greed for a reason. Unless arrangements were already made prior to pulling the boss, this is not bad etiquette, no matter how much you repeat yourself. If somebody wants a piece of gear, speak up and ask. That's proper etiquette. Now if the other members of the party say no, that's something else. How are you equating a literal greed option to being a decent human? That's a ridiculous stretch, and I've made some crazy stretches before on the forums.

It actually really is lol.. You can't even trade Byakko weapons and Sigma gear in for seals yet, can you? What use do you have for them? What are you actually lotting on them for? To lower your inventory space by one? Why would you lot on something that has no use to you?
It absolutely is called "Greed", doesn't mean that you should use it to lot against someone who can actually use it.

I mean do you not know what etiquette actually means? Etiquette is often unspoken, and dictates what is considered polite. If you don't think "Oh this weapon or item is relevent for those who can actually use it at the moment, I am going to pass to allow those who can actually use it" is not the proper way to be polite, then I don't know what to tell you..
However I don't expect people to follow the oldschool etiquette since it has obviously changed over the years. I am just using this very example (again) to highlight part of the OP's observation as to the greedy mentality of the NA culture.

if I want the SMN tome in Byakko, and I'm going in as DRG because that's my only 340 job, then yeah, I'm gonna greed on SMN because I need it for that job. Instead of assuming, I will speak up and ask for others not to draw on it.

Good for you. However how much nicer would it be if you had faith in humanity and those that cannot actually use the item for anything currently, to just pass instead?
That is my entire point.

I am not refuting that what you are saying is considered normal behaviour. I am saying that it is poor etiquette (which is valid) and it is purely a greed mentality that is brought on by cultural influences.
And you not thinking it is poor etiquette is part of my entire point. NA culture doesn't see greed mentality as bad.
