rebuilding post collapse.

Hunters and gatherers died off because those that embraced farming had armies and those armies killed them off. Think about the Inca empire and how they crushed the local tribes that wouldn't join with them. They did that by embracing farming. Massed farming allowed them to feed more people, which needed larger armies for more land protection, which needed more food, and it's a big circle. The thing is, the circle worked fine.

Farming led to over population, but it also led to the massive development in technology that we enjoy today.

It doesn't take many people to work a farm. Britain's largest chicken farms have fewer than 40 employees. Granted there's infrastructure in place to assist, e.g. grain deliveries and the alike. But a lot of farming has a pretty low manpower need. A few people can provide for a lot of others.

A group of 100 people could happily feed 1000.
