You don’t have a Constitutional right to start a business.
We don't?
It is no accident that a nation conceived in liberty and dedicated to justice for all protects property rights. Property is the foundation of every right we have, including the right to be free. Every legal claim, after all, is a claim to something—either a defensive claim to keep what one is holding or an offensive claim to something someone else is holding.
John Locke, the philosophical father of the American Revolution and the inspiration for Thomas Jefferson when he drafted the Declaration of Independence, stated the issue simply: ‘‘Lives, Liberties, and Estates, Property Rights and the Constitution which I call by the general Name, Property.’’ And James Madison, the principal author of the Constitution, echoed those thoughts when he wrote that ‘‘as a man is said to have a right to his property, he may be equally said to have a property in his rights.’’
Much moral confusion would be avoided if we understood that all of our rights—all of the things to which we are ‘‘entitled’’—can be reduced to property. That would enable us to separate genuine rights—things to which we hold title—from specious ‘‘rights’’—things to which other people hold title, which we may want.
It was the genius of the old common law, grounded in reason, that it grasped that point. And the common-law judges understood a pair of corollaries as well: that property, broadly conceived, separates one individual from another, and that individuals are independent or free to the extent that they have sole or exclusive dominion over what they hold. Indeed, Americans go to work every day to acquire property just so they can be independent.
