Much of the basic and applied research that is carried out in the United States is funded by the federal government and takes place in university centres. The results of this research serve as a knowledge base for private enterprise. This arrangement is intended to benefit the public by the introduction of new goods and services and to benefit private enterprise by the profits it derives from such goods and services. What sustains this arrangement is the existence of laws and legal transactions which recognize claims concerning licences, patents and private property.

Locke's views were based on his belief in natural rights, foremost of which is the right to property. Civil government is a fiduciary trust created by a social contract for the protection of natural rights. Locke's natural rights and social contract theory were completely rejected by Utilitarianism.

The Utilitarian John Stuart Mill observed that, "Private property, in every defence made of it, is supposed to mean, the guarantee to individuals of the fruits of their own labour and abstinence" (Mill, 1893). With the notable exception of the Marxists, who use labour theory to attack the institution of private
