CHAPTER X.
OF INTERFERENCES OF GOVERNMENT GROUNDED ON
ERRONEOUS THEORIES.
§ 1.From the necessary functions of government, and the effects produced on the economical interests of society by their good or ill discharge, we proceed to the functions which belong to what I have termed, for want of a better designation, the optional class; those which are sometimes assumed by governments and sometimes not, and which it is not unanimously admitted that they ought to exercise.
Before entering on the general principles of the question, it will be advisable to clear from our path all those cases, in which government interference works ill because grounded on false views of the subject interfered with. Such cases have no connexion with any theory respecting the proper limits of interference. There are some things with which governments ought not to meddle, and other things with which they ought; but whether right or wrong in itself, the interference must work for ill, if government, not understanding the subject which it meddles with, meddles to bring about a result which would be mischievous. We will therefore begin by passing in review various false theories, which have from time to time formed the ground of acts of government more or less economically injurious.
Former writers on political economy have found it needful to devote much trouble and space to this department of their subject. It has now happily become possible, at least in our own country, greatly to abridge this purely negative part of our discussions. The false theories of political economy which have done so much mischief in times past, are entirely discredited among all who have not lagged behind
