Nearly a century ago, the great economist Ludwig von Mises observed that massive central bank easing is invariably a form of cowardice that attempts to avoid the need to restructure debt or correct fiscal deficits, avoiding wiser but more difficult choices by instead destroying the value of the currency.
Von Mises wrote, “A government always finds itself obliged to resort to inflationary measures when it cannot negotiate loans and dare not levy taxes, because it has reason to fear that it will forfeit approval of the policy it is following if it reveals too soon the financial and general economic consequences of that policy. Thus inflation becomes the most important psychological resource of any economic policy whose consequences have to be concealed; and so in this sense it can be called an instrument of unpopular, that is, of antidemocratic policy, since by misleading public opinion it makes possible the continued existence of a system of government that would have no hope of the consent of the people if the circumstances were clearly laid before them. That is the political function of inflation. When governments do not think it necessary to accommodate their expenditure and arrogate to themselves the right of making up the deficit by issuing notes, their ideology is merely a disguised absolutism.”
As a side note, von Mises also cautioned against the misconception that destroying the value of a currency would have a sustainable benefit for the economy, writing “If the depreciation is desired in order to ‘stimulate production’ and to make exportation easier and importation more difficult in relation to other countries, then it must be borne in mind that the ‘beneficial effects’ on trade of the depreciation of money only last so long as the depreciation has not affected all commodities and services. Once the adjustment is completed, then these ‘beneficial effects’ disappear. If it is desired to retain them permanently, continual resort must be had to fresh diminutions of the purchasing power of money.”
