Judging from the general numbers of successful individuals having been nurtured in "rich" environments (e.g. you'll find _much_ more kids going on to college in suburban schools than in inner-city schools), I would guess that either 1) the importance of success and the things that are required to achieve that success are clear to them - and so, they're better set to make wise, informed decisions, or 2) they've already gotten into a good work ethic - and if you're there, then it's easy - you largely have it made.
