I think this is it. You hear the stories about the 15 year olds with successful internet businesses because it's pretty rare, but they are really not the norm at all. Most 15 year olds are just mindless consumers of the internet, in the form of Twitter, Instagram, Facebook, etc.

30 years ago the same kid would have worked out a way to have 10 neighborhood newspaper routes and subcontract the actual delivery work to other kids, keeping a commission.
