Meh, the 70s had half the world population that we have now, and created much of the kick-ass music and arts that we still hold in high value. And, to be honest, a 3b pencil is really a luxury first world problem. Besides, the more important metric for that will be population density. In a city of 100000 or more, it makes sense to have a dedicated arts and crafts store, maybe even more. In a village of 1000, not so much.
