Oh my god, you're right. I watched Scooby Doo for over a decade and this never occurred to me. Where do they sleep? Huddled in the back of the van? Where are they getting income -- they must have money for all of those Scooby Snacks? Panhandling? Stealing? Prostitution? How did this group of presumably unrelated teenagers come into this situation? My mind is being blown by all of the questions conjured by your simple childhood realization.
