See, the thing is, any large growth tends to come from 3rd world places. Desperate people grasping at the (false) hope that paradise, which is coming Soon™, will solve all their problems.
The apathy and bleed-off of the born-ins, along with the gradual death of all the old-timers, is happening in large part in first-world countries (USA, Europe, etc.).
The problem becomes economic. If support from the rich countries dries up, they can't fund their massive printing operation. Boom. Collapse.
They seem to be trying to solve this but putting stuff online. Problem is, folks in grass and mud huts with chickens running in the yard don't have internet and likely never will.
