The essential difference between rich societies and poor societies does not stem from any greater effort the former devote to work, nor even from any greater technological knowledge the former hold. Instead it arises mainly from the fact that rich nations possess a more extensive network of capital goods wisely invested from an entrepreneurial standpoint. These goods consists of machines, tools, computers, buildings, semi-manufactured goods, software, etc., and they exist due to prior savings of the nation's citizens. In other words, comparatively rich societies possess more wealth because they have more time accumulated in the form of capital goods, which places them closer in time to the achievement of much more valuable goals.
