An ‘automatic’ gold currency is part and parcel of a laissez-faire and free-trade economy. It links every nation’s money rates and price levels with the money-rates and price levels of all the other nations that are ‘on gold.’ It is extremely sensitive to government expenditure and even to attitudes or policies that do not involve expenditure directly, for example, to foreign policy, to certain policies of taxation, and, in general, to precisely all those policies that violate the principles of [classical] liberalism. This is the reason why gold is so unpopular now and also why it was so popular in a bourgeois era. It imposes restrictions upon governments or bureaucracies that are much more powerful than is parliamentary criticism. It is both the badge and the guarantee of bourgeois freedom—of freedom not simply of the bourgeois interest, but of freedom in the bourgeois sense. From this standpoint a man may quite rationally fight for it, even if fully convinced of the validity of all that has ever been urged against it on economic grounds. From the standpoint of etatisme and planning, a man may not less rationally condemn it, even if fully convinced of the validity of all that has ever been urged for it on economic grounds.
