The idea of social justice is that the state should treat different people unequally in order to make them equal.

The advantage of a free market is that it allows millions of decision-makers to respond individually to freely determined prices, allocating resources - labor, capital and human ingenuity - in a manner that can't be mimicked by a central plan, however brilliant the central planner.

The system of private property is the most important guaranty of freedom, not only for those who own property, but scarcely less for those who do not.

It is also true that the less possible it becomes for a man to acquire a new fortune, the more must the existing fortunes appear as privileges for which there is no justification. Policy is then certain to aim at taking these fortunes out of private hands, either by the slow process of heavy taxation of inheritance or by the quicker one of outright confiscation. A system based on private property and control of the means of production presupposes that such property and control can be acquired by any successful man.

We must raise and train an army of fighters for freedom.
