given our current economic model you are correct, there is no way people will go to work on the land for such a small financial return. However, our current economic model is predicated upon and underpinned by cheap oil. 1 litre of oil does the work of a person working for something like 35 hours, yet it costs about £1 per litre. We are at the end of the age of cheap oil, and oil production will not be able to keep up with demand, therefore we will see significant price shocks. Food will cost more and people will have less money, we will see a massive change in how our society is structured and how goods and services are distributed. I personally know people who would love to be free to work the land and grow food but are trapped in our current system of debt slavery, so they are out there. I'm guessing for when they get hungry will be a good motivator for those who don't want to work for their bread.
re the beards, I think it's compulsory to be a weirdy beardy in this field, even for the women.
