Individualism and nuclear families prevent people from achieving economies of scale in housing, child rearing and consumption; and so they remain dependent on a continuous flow of income (poor).
A young couple had joined an early pollykaryote*, but wanting no children though fearing for their investment, they convinced their fellow members to adopt talented orphans and pay for their education in the hope they would in time strengthen the polity.
The first studied sociology and over the years proposed changes to the pollykaryote’s code that increased its cohesiveness and economic defenses to the point that its wealth grew ten-fold. The second studied engineering and then business, returning well over five times what es schools had cost.
The last had wanted to become a doctor, but gradually became lazy and eventually failed es final examinations. The couple summoned the orphan and berated e: “We paid for your entire education and you couldn’t even graduate. What ever happened?” The youth answered through clenched teeth: “I knew you were selfish and only funded my studies to ensure your own financial success, so i became resentful and lost heart.” The couple replied: “If you knew we were selfish, you should at least have worked to pass your exams and repay your debt. Now you will never be received into the safety of our polity, but will instead be cast out with nothing at all into the uncaring world where we found you.”
