rebuilding post collapse.

[bigpaul]

there are less people in farming because 1. they can earn more money sitting at a computer, and 2. we have mechanisation, with huge tractors and combines a lot of work can be done with fewer people. post collapse everything will have to be done by hand, or by using horses as it was before the first world war, it will be labour intensive, so the scale of any enterprise will depend on how many in any group and indeed on the overall survival rate.
