I'm not disagreeing with you. But given silisili's lived experience of dealing with 30lb backpacks, chrisco255's statement about that being 'good for you' is simply not correct, unless perhaps that kid is a high school football player weighing 200+ lbs.

Also, only nerds and dweebs use both shoulder straps.

Rather, I don't think it's a simple matter of education, given that there are also social pressures involved.
