In more developed countries, gamification is "put each kind of garbage in its own can" (in half of that world, those cans are still emptied to the same trash truck).

I don't think the recycling schemes (illusory and otherwise) were introduced on the assumption that the public would get so addicted to rubbish separation that we'd eventually be able to eliminate the need for any paid garbage collectors though. Or indeed that many people don't view rubbish separation as 'work' imposed on them, to the extent many local authorities collecting household waste have to threaten fines or at least noncollection of waste to enforce compliance.

As for less developed countries, they usually have an abundance of flytipped waste because they don't pay [enough] garbage collectors and whilst there's the occasional eyecatching 'clean up this beauty spot' activity nobody wants to play the garbageman game all year round...
