Right-libertarianism, also known as libertarian capitalism, or right-wing libertarianism, is a libertarian political philosophy that supports capitalist property rights and defends market distribution of natural resources and private property. The term right-libertarianism is used to distinguish this class of views on the nature of property and capital from left-libertarianism, a type of libertarianism that combines self-ownership with an egalitarian approach to property and income. In contrast to socialist libertarianism, right-libertarianism supports free-market capitalism. Like most forms of libertarianism, it supports civil liberties, especially natural law, negative rights, the non-aggression principle, and a major reversal of the modern welfare state.
