A critical error of the Left
As Labour pours another £11bn of poison into the wells, I find myself reflecting on the economics of the Left, people who seem to be lamenting coming “Tory cuts” after so much “Labour investment”.
In the first place, Labour plan their own substantial cuts. More to the point, Labour’s spending was funded not by sustainable prosperity, but by one long credit expansion unbacked by real savings, which has now, inevitably, come to an end.
Left-wingers’ admirable intentions seem to be unmatched by a reasonable understanding of the means to bring about the good ends they intend.
The shortest and surest way to understand basic economics is, purportedly, Henry Hazlitt’s famous Economics in One Lesson:
Today is already the tomorrow which the bad economist yesterday urged us to ignore. The long-run consequences of some economic policies may become evident in a few months. Others may not become evident for several years. Still others may not become evident for decades. But in every case those long-run consequences are contained in the policy as surely as the hen was in the egg, the flower in the seed.
From this aspect, therefore, the whole of economics can be reduced to a single lesson, and that lesson can be reduced to a single sentence:
The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups.
Nine-tenths of the economic fallacies that are working such dreadful harm in the world today are the result of ignoring this lesson. Those fallacies all stem from one of two central fallacies, or both: that of looking only at the immediate consequences of an act or proposal, and that of looking at the consequences only for a particular group to the neglect of other groups.
