Like crabs, states have mandatory expenses that they must pay first, before they can shunt resources into weapons. Crabs are made from millions of cells, which need to be fed and protected. If the cells die, the crab dies, and most of its mandatory expenditures revolve around keeping these cells alive. States are made up of people, and necessary expenses protect and nurture these people—things such as education and welfare, police forces and highways. Only when funds are left over after mandatory expenses are accounted for can states invest in militaries, weapons, and other luxury items.
