writers that are rich may experience graffiti differently, and be even more drawn to it because graffiti will make them do things they would never do otherwise. if u've been hustling on the street all ur life, then graffiti won't offer u much more than u've already exerienced, however if you've grown up in a nice neighborhood, and have never had to work hard to get anything...graffiti will be a thrill, something out of the ordinary.
and yes rich kids do have it easier, but does it make them less of a writer? no! nothing's stoping you from getting rich, you just gotta trade the passion you have for graffiti, for passion for making money!
im not rich or even well off, but do plan to become one day!
