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:
Mr. de Montalembert [politician and writer] adopting the thought contained in a famous proclamation by Mr. Carlier, has said: "We must make war against socialism." According to the definition of socialism advanced by Mr. Charles Dupin, he meant: "We must make war against plunder."
But of what plunder was he speaking? For there are two kinds of plunder: legal and illegal.
I do not think that illegal plunder, such as theft or swindling — which the penal code defines, anticipates, and punishes — can be called socialism. It is not this kind of plunder that systematically threatens the foundations of society. Anyway, the war against this kind of plunder has not waited for the command of these gentlemen.
The war against illegal plunder has been fought since the beginning of the world. Long before the Revolution of February 1848 — long before the appearance even of socialism itself — France had provided police, judges, gendarmes, prisons, dungeons, and scaffolds for the purpose of fighting illegal plunder. The law itself conducts this war, and it is my wish and opinion that the law should always maintain this attitude toward plunder.
But it does not always do this. Sometimes the law defends plunder and participates in it. Thus the beneficiaries are spared the shame, danger, and scruple which their acts would otherwise involve. Sometimes the law places the whole apparatus of judges, police, prisons, and gendarmes at the service of the plunderers, and treats the victim — when he defends himself — as a criminal. In short, there is a legal plunder, and it is of this, no doubt, that Mr. de Montalembert speaks.
This legal plunder may be only an isolated stain among the legislative measures of the people. If so, it is best to wipe it out with a minimum of speeches and denunciations — and in spite of the uproar of the vested interests.
