Among the numerous luxuries of the table...coffee may be considered as one of the most valuable. It excites cheerfulness without intoxication; and the pleasing flow of spirits which it occasions...is never followed by sadness, languor or debility.
Benjamin FranklinThe riches of a country are to be valued by the quantity of labor its inhabitants are able to purchase, and not by the quantity of silver and gold they possess; which will purchase more or less labor, and therefore is more or less valuable, as is said before, according to its scarcity or plenty.
Benjamin Franklin
