it's not how much money you have (or don't) it's how you carry yourself........ although I kinda look down on punks that say they've had it rough, but really they're just trying to get attention (like my old roommate's fiancee, her dad makes 12 mil a year), your financial situation shouldn't matter.
I don't think you necessarily have to be dirt ass poor *but it helps.LOL* but I think you do have to have had a life of struggle and hardship to be able to REALLY relate to that lifestyle.
Technically wouldn't that apply to just about anything though? Plus many use the "life of struggle and hardship" as an excuse to do some pretty fucked up things...like members of street gangs. Lord knows they love to cache' on their hard knock life while in court.
