1.16. The more Labor there is in a State, the more the State is Judged Naturally Rich
The wealth of a nation depends on putting the labor force to work. Those who are unnecessary for farming can be employed in making higher quality products and manufactured goods, particularly durable goods made from metal. Saving is the key determinant of wealth and gold is a particularly useful form of savings because it can purchase all things, even in time of war. The prince and property owners determine how people will be employed by their consumption choices, while the Catholic Church reduces the resources available to materially sustain the people.
