Frederic Bastiat was a French economist and statesman. During and after the Revolution in 1848, he warned of the inevitable degeneration of socialism into communism in The Law. Previous Bastiat posts can be found here.
From The Law:
But how is this legal plunder to be identified? Quite simply. See if the law takes from some persons what belongs to them, and gives it to other persons to whom it does not belong. See if the law benefits one citizen at the expense of another by doing what the citizen himself cannot do without committing a crime.
Then abolish this law without delay, for it is not only an evil itself, but also it is a fertile source for further evils because it invites reprisals. If such a law — which may be an isolated case — is not abolished immediately, it will spread, multiply, and develop into a system.
The person who profits from this law will complain bitterly, defending his acquired rights. He will claim that the state is obligated to protect and encourage his particular industry; that this procedure enriches the state because the protected industry is thus able to spend more and to pay higher wages to the poor workingmen.
Do not listen to this sophistry by vested interests. The acceptance of these arguments will build legal plunder into a whole system. In fact, this has already occurred. The present-day delusion is an attempt to enrich everyone at the expense of everyone else; to make plunder universal under the pretense of organizing it.
