The right ordering of economic life cannot be left to a free competition of forces. For from this source, as from a poisoned spring, have originated and spread all the errors of individualist economic teaching. Destroying through forgetfulness or ignorance the social and moral character of economic life, it held that economic life must be considered and treated as altogether free from and independent of public authority…. But free competition, while justified and certainly useful provided it is kept within certain limits, clearly cannot direct economic life—a truth which the outcome of the application in practice of the tenets of this evil individualistic spirit has more than sufficiently demonstrated.
