From The Law:
It is impossible to introduce into society a greater change and a greater evil than this: the conversion of the law into an instrument of plunder.
What are the consequences of such a perversion? It would require volumes to describe them all. Thus we must content ourselves with pointing out the most striking.
In the first place, it erases from everyone's conscience the distinction between justice and injustice.
No society can exist unless the laws are respected to a certain degree. The safest way to make laws respected is to make them respectable. When law and morality contradict each other, the citizen has the cruel alternative of either losing his moral sense or losing his respect for the law. These two evils are of equal consequence, and it would be difficult for a person to choose between them.
The nature of law is to maintain justice. This is so much the case that, in the minds of the people, law and justice are one and the same thing. There is in all of us a strong disposition to believe that anything lawful is also legitimate. This belief is so widespread that many persons have erroneously held that things are "just" because law makes them so. Thus, in order to make plunder appear just and sacred to many consciences, it is only necessary for the law to decree and sanction it. Slavery, restrictions, and monopoly find defenders not only among those who profit from them but also among those who suffer from them.
