They must all be rich if all of them have houses with basements, computers, and can afford to smoke pot everyday.
The way I see it: The parents (or at least one) is on disability and getting a monthly check. The kids (at least one) are getting SS because the parent can't work, getting a monthly "crazy check" from ADD or ADHD due to the parent smoking pot when they were a baby. The house is section 8 (HUD or government subsidized). The parent who isn't collecting disability is on welfare due to being the only capable wage earner in the home, but has to take care of the others.
So that's... disability check, S.S. check, "crazy" check, welfare check, government paid rent, not to mention WIC, access, or other government food program... living off the taxpayers must be a great way to live.
