We are talking about the wasteland setting, why are you bringing up examples that don't even apply to the game?
Well the first time I mentioned a foreigner asking for directions you didn't say anything
also a suit counts as a boost, liek takign mentats.
I disagree, only a person who knows how to do some fast-talk and act, could get the suit and think about using it as part of his attempt to convince the dude that he's a company man, etc. The suit in itself gives no boost: a guy who's not charismatic might get the suit, would possibly be able to walk past most people without trouble (as they'd think he is a company man), but when he actually has to talk and convince, or is talked to, he will be in a problem no matter what he's wearing ("Hey! who are you? Can't quite say I know that face" - "Oh that's, um, yeah, 'cause, I'm [...]"). Getting some expensive suit *allows* you to try that story, but it doesn't really *help* you in your attempt to convince others that the story is true.
Now about the rest you said, especially this part:
And if the characters is a tribal, and we knwo Tribals are looked down by a lot of peopel in the Fallout world, he is from the begining in a disadvantage
I do admit it makes sense. But my conclusion is that New Vegas does not really offer the possibility to play certain roles like this. It would be easier, for example, if you could choose a background at the beginning of the game, and if you choose Tribal, you'll notice a change in the first reactions of most non-tribals. You know, something like the Sex Appeal trait from Fallout 2.
Low barter or speech mean the character, let's say, "inherently" sucks at those activities, when he could be a trader who has no problem while trading with other tribals, but always fails with other communities due to their prejudice, or whatever. Same with Charisma, he might be a shaman or a tribe elder, who the members of his tribe stick to because of the power of his words and always listen to him, but that doesn't count when he's around non-tribals who won't listen to him because they think he's a "savage".
But like I said, this last part is not really "against" what you said. I'm only saying that in order to be able to play some roles we would need certain mechanics to enhance the Roleplaying possibilities of this game. But we don't have them so we have to opt for other solutions like low Charisma, Barter, Speech, which kinda means sticking to stereotypes (hurr durr savage tribal with spear!)
