Bastiat, is referred to in some of the reviews as being liberal but the modern meaning of his thinking is libertarian, which makes a world of difference. In Bastiat's first essay in the book he keeps referring to the seen and unseen results of government actions and I think that he draws the wrong conclusions, much as modern day libertarians do.
Always he claims that the unseen results of government actions are bad or at least unpleasant. He also argues that private enterprise could do the same thing more efficiently but he does not look deep enough nor far enough into the future. Armies, mail and the money supply are just three of dozens of things that government does best; at least in the initial phase.
