> In the modern world, natural resources are the limiting factor of production. It takes only a tiny percentage of the population to farm the arable land, mine iron ore, cut down and process the timber, and extract the oil. A somewhat larger percent converts those resources into the necessities of life – bread, vehicles, homes, roads, bridges, clothing, furniture, stocked grocery aisles, appliances, etc. The worker entering the economy has a problem. They must find a source of income so they can access resources and manufactured goods. But there are no unexploited resources and no surplus jobs to be had processing those resources. They need a job, but their labor is surplus and unnecessary. This is the real problem. Everyone but a tiny percentage of the population is ... well ... not needed at all.
