The Wealth of Nations by Adam Smith is a great book. My favorite part is Book III, Chapter 4 on the end of feudalism. In particular, I like these two paragraphs:
In a country which has neither foreign commerce, nor any of the finer manufactures, a great proprietor, having nothing for which he can exchange the greater part of the produce of his lands which is over and above the maintenance of the cultivators, consumes the whole in rustic hospitality at home. If this surplus produce is sufficient to maintain a hundred or a thousand men, he can make use of it in no other way than by maintaining a hundred or a thousand men. He is at all times, therefore, surrounded with a multitude of retainers and dependants, who, having no equivalent to give in return for their maintenance, but being fed entirely by his bounty, must obey him, for the same reason that soldiers must obey the prince who pays them. … In a country where there is no foreign commerce, nor any of the finer manufactures, a man of ten thousand a year cannot well employ his revenue in any other way than in maintaining, perhaps, a thousand families, who are all of them necessarily at his command. In the present state of Europe, a man of ten thousand a year can spend his whole revenue, and he generally does so, without directly maintaining twenty people, or being able to command more than ten footmen not worth the commanding. Indirectly, perhaps, he maintains as great or even a greater number of people than he could have done by the ancient method of expense. For though the quantity of precious productions for which he exchanges his whole revenue be very small, the number of workmen employed in collecting and preparing it must necessarily have been very great. Its great price generally arises from the wages of their labour, and the profits of all their immediate employers. By paying that price he indirectly pays all those wages and profits and thus indirectly contributes to the maintenance of all the workmen and their employers. He generally contributes, however, but a very small proportion to that of each, to very few perhaps a tenth, to many not a hundredth, and to some not a thousandth, nor even a ten-thousandth part of their whole annual maintenance. Though he contributes, therefore, to the maintenance of them all, they are all more or less independent of him, because generally they can all be maintained without him.
