Economically, this means free market capitalism - laissez faire, laissez passez. Theory of Rights - Rights are claims to freedom of action. The only way rights can be violated is by aggression. If a person adheres to the NAP then he cannot violate rights. Thus claims of 'rights' to housing, food, and education are counterfeit, and amount to a contradictory 'right to enslave'.
Authority is aggression.
Various state actions violate the NAP, including taxation, conscription, and regulation of the market. If an action is voluntary, then it is not an act of authority. Class struggle - The usefulness of class theory is debatable, since it ignores the diverse interests of people artificially subsumed in each class. However, occasionally class analysis can be useful. The two antagonistic classes are the producers and the parasites.
