Too many white lies and white lines
The rich kids lie just for the heck of it. The kids lie to their parents about their behaviour (drugs, grades, etc.) so their parents stay off their backs.
As they’re wealthy, these kids have an easier time getting a hold of cocaine (white lines), the rich person’s drug.
