— James Madison 4th president of the United States (1809 to 1817) 1751 - 1836
1780s, Context: The man who is possessed of wealth, who lolls on his sofa or rolls in his carriage, cannot judge the wants or feelings of the day-laborer. The government we mean to erect is intended to last for ages. The landed interest, at present, is prevalent; but in process of time, when we approximate to the states and kingdoms of Europe, — when the number of landholders shall be comparatively small, through the various means of trade and manufactures, will not the landed interest be overbalanced in future elections, and unless wisely provided against, what will become of your government? In England, at this day, if elections were open to all classes of people, the property of landed proprietors would be insecure. An agrarian law would soon take place. If these observations be just, our government ought to secure the permanent interests of the country against innovation. Landholders ought to have a share in the government, to support these invaluable interests, and to balance and check the other. They ought to be so constituted as to protect the minority of the opulent against the majority. The senate, therefore, ought to be this body; and to answer these purposes, they ought to have permanency and stability.
