Labor

 Inasmuch as most good things are produced by labor, it follows that all such things ought to belong to those whose labor has produced them. But it has happened in all ages of the world that some have labored, and others, without labor, have enjoyed a larger proportion of the fruits. This is wrong, and should not continue. To secure to each laborer the whole product of his labor as nearly as possible is a worthy object of any good government.
