There are basically only two ways in which economic life can be organized. The first is by the voluntary choice of families and individuals and by voluntary cooperation. This arrangement has come to be known as the free market. The other is by the orders of a dictator. This is a command economy. In its more extreme form, when an organized state expropriates the means of production, it is called socialism or communism. Economic life must be primarily organized by one system or the other.
It can, of course, be a mixture, as it unfortunately is in most nations today. But the mixture tends to be unstable. If it is a mixture of a free and a coerced economy the coerced section tends constantly to increase.
One qualification needs to be emphasized.
