Americans have four basic ways of solving problems that are too big for individuals to handle by themselves. One is through the federal government. A second is through state governments and the local governments that the states create. The third is through the private sector – the economic sector that includes business, agriculture, and labor. The fourth method is the independent sector – the voluntary, cooperative action of free individuals and independent association. Voluntary action is the most powerful of these, because it is uniquely capable of stirring the people themselves and involving their enthusiastic energies, because it is their own – voluntary action is the people's action. ... As Woodrow Wilson said, "The most powerful force on earth is the spontaneous cooperation of a free people." Individualism makes cooperation worthwhile – but cooperation makes freedom possible.
