Economics in One Lesson is an introduction to economics written by Henry Hazlitt and first published in 1946. It is based on Frédéric Bastiat's essay (English: "What is Seen and What is Not Seen").Called Hazlitt's "most enduring contribution," the book has sold nearly one million copies and is available in at least ten languages. See: ;
The "One Lesson" is stated in Part One of the book: "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." Part Two consists of twenty-four chapters, each demonstrating the lesson by tracing the effects of one common economic belief, and exposing common economic belief as a series of fallacies.
Among its policy recommendations are the advocacy of free trade, an opposition to price controls, an opposition to monetary inflation, and an opposition to fiscal policy, such as stimulative governmental expenditures, arguing: There are men regarded today as brilliant economists, who deprecate saving and recommend squandering on a national scale as the way of economic salvation; and when anyone points to what the consequences of these policies will be in the long run, they reply flippantly, as might the prodigal son of a warning father: 'In the long run we are all dead.' And such shallow wisecracks pass as devastating epigrams and the ripest wisdom.
Summary In the preface to "Economics in One Lesson," Henry Hazlitt explains that the book is a critical analysis of economic fallacies that are prevalent and have become a new orthodoxy. The book seeks to dissect and expose these errors, particularly the central error from which they stem. Hazlitt argues that the shortest and surest way to understand economics is through a dissection of such errors. He states that this book is primarily one of exposition and makes no claim to originality with regard to any of the chief ideas that it expounds. Hazlitt acknowledges his indebtedness to Frédéric Bastiat, Philip Wicksteed, and Ludwig von Mises, whose ideas have influenced the present work. He also mentions that when analyzing fallacies, he has thought it less advisable to mention particular names than in giving credit. The object of this book is not to expose the special errors of particular writers, but economic errors in their most frequent, widespread, or influential form. Hazlitt concludes by saying that he hopes that the book will be forgiven for making rare reference to statistics as he believes that those who are interested in specific economic problems are advised to read current "realistic" discussions of them, with statistical documentation.
Chapter 1, "The Lesson", explains that economics is a field filled with fallacies because of the difficulties inherent in the subject and the special pleading of selfish interests. Every group has economic interests antagonistic to other groups. Another factor is the tendency of people to overlook the secondary consequences of a policy, focusing only on the immediate effects on a specific group. The difference between good and bad economics lies in the ability to look beyond the immediate effects and consider the longer-term and indirect consequences for all groups. Nine-tenths of economic fallacies arise from ignoring this lesson. Finally, the art of economics consists of looking not just at the immediate effects of a policy but at its longer-term effects for all groups.
Chapter 2, "The Broken Window", uses the example of a broken window to demonstrate what Hazlitt considers the fallacy that destruction can be good for the economy. He argues that while the broken window may create work for the glazier, the money the shopkeeper has to spend on replacing the window means that he cannot spend it elsewhere in the economy, such as on a new suit from a tailor. The potential business for the tailor is lost, and the community is worse off overall. Hazlitt stresses the importance of considering all parties involved in an economic transaction, not just those immediately visible.
Chapter 3, "The Blessings of Destruction", discusses what Hazlitt considers the persistent fallacy of the broken window, which is often used to justify the benefits of destruction, particularly in times of war. He points out that although destruction may lead to a need for rebuilding, it does not necessarily lead to effective demand or increased purchasing power, as it diverts demand from one area to another. Additionally, wartime inflation, which people may perceive as good economic results, can be produced just as well by peacetime inflation. Finally, the supply of goods is what constitutes demand in an exchange economy, and wartime destruction inevitably leads to a shrinking in total demand.
Chapter 4, "Public Works Mean Taxes", examines what Hazlitt considers the fallacy of government spending as a solution to economic problems. Hazlitt argues that every dollar of government spending must be raised through a dollar of taxation. Public works, such as streets and roads, armories, and buildings for essential government services are necessary, but public works built primarily "to provide employment" are problematic. When employment becomes the end, need becomes a subordinate consideration, and "projects" have to be invented. Hazlitt concludes that for every public job created by a government project, a private job has been destroyed somewhere else. He argues that government spending is not a panacea and must be viewed in the larger context of secondary consequences, including jobs destroyed by taking money from taxpayers.
Chapter 5, "Taxes Discourage Production", argues that taxes discourage production and have a negative impact on the economy. The government cannot simply take money from one person and give it to another without consequences. Taxes affect the actions and incentives of those from whom they are taken, and high taxes discourage risk-taking and entrepreneurship, resulting in fewer new jobs and less economic growth. While some taxes are necessary for essential government functions, excessive taxes are counterproductive and discourage private production and employment. The government cannot solve the problem of unemployment by creating it through excessive taxation.
Chapter 6, "Credit Diverts Production", discusses the dangers of government "encouragement" to businesses in the form of direct grants of government credit or guarantees of private loans. He focuses on government loans to farmers, explaining that proposals for more credit are really proposals for increased debt. Hazlitt argues that loans made by private lenders differ from those made by government agencies because private lenders risk their own funds and are careful to investigate the assets and business acumen of the borrower, whereas government lenders take risks with taxpayers' money that private lenders will not take. Hazlitt concludes that the faith in government lending policies springs from two acts of shortsightedness: looking at the matter only from the standpoint of the borrowers and thinking only of the first half of the transaction.
Hazlitt argues against the idea of government assuming risks that are "too great for private industry." This would lead to favoritism, scandals, and an increase in demand for socialism. Hazlitt states that government loans and subsidies to businesses would waste capital and reduce production. Private lenders are cautious with their money and investigate proposals before investing in them, while government lenders are likely to make mistakes and invest in inefficient projects. Government loans and subsidies would tax successful private businesses to support unsuccessful ones, which is not a paying proposition in the long run.
Chapter 7, "The Curse of Machinery", discusses what Hazlitt considers the myth that machines create unemployment. Hazlitt notes that the belief that machines cause unemployment leads to preposterous conclusions, and cites Adam Smith's "Wealth of Nations," which shows how machinery revolutionized pin-making and increased productivity. Hazlitt also highlights that the Industrial Revolution was met with resistance, particularly in the stocking industry, where machines were destroyed, and the inventors were threatened. Nevertheless, the number of people employed in the cotton industry increased by 4,400%, and technological advances in the maritime and steel industries were met with pessimism, but ultimately led to more efficient production methods.
Hazlitt discusses what he considers the fallacy that labor-saving machinery and technical progress lead to unemployment and misery. The author argues that the introduction of such machinery can increase employment and benefit society. The author uses the example of a clothing manufacturer who adopts a machine that reduces the labor required to make overcoats. Although half of the labor force may be dropped, the manufacturer would have only adopted the machine if it would have saved labor in the long run. After the machine has produced economies sufficient to offset its cost, the manufacturer has more profits than before, which can be used to expand operations, invest in other industries, or increase personal consumption. In any case, these extra profits indirectly provide jobs, and competition among manufacturers can lead to further employment opportunities.
Hazlitt argues that the fear of machines taking jobs is unfounded. He explains that machines do not necessarily replace workers, but they increase production and, thus, raise the standard of living. He gives examples of newly created trades in the past that have created more jobs as the product was improved and the cost reduced. Hazlitt also notes that machines have significantly increased the population of the world as they made it possible to support it. Hazlitt warns, however, that we should not only focus on the long-run and broad view but also consider the immediate effects on certain groups of people. While some may lose jobs, others may gain them or benefit from the increased production and lower prices. Finally, Hazlitt emphasizes that the primary function of machines is to increase production and economic welfare, not necessarily to create jobs.
Chapter 8, "Spread-The-Work Schemes", discusses what Hazlitt considers the economic fallacy that creating jobs is an end in itself. He argues that this belief is often used to justify inefficient and uneconomical practices, such as the arbitrary subdivision of labor in unions. The author also examines various schemes to "spread the work," such as shortening the working week, which are proposed to create more jobs. However, he argues that such schemes often lead to a reduction in productivity, and may not necessarily create more jobs. Ultimately, the author contends that the focus should be on increasing productivity, which leads to increased wealth and a higher standard of living for everyone.
Chapter 9, "Disbanding Troops and Bureaucrats", discusses the fear of unemployment that arises when millions of soldiers are released into the labor market after a war. Hazlitt argues that the fear is misplaced because the soldiers will become self-supporting civilians, and their release from the army will free up funds for taxpayers to buy additional goods, increasing civilian demand and employment. Similarly, he argues that the same reasoning applies to civilian government officials who are not performing services for the community reasonably equivalent to the remuneration they receive. Removing unnecessary officeholders will not cut down on the national income, but instead, will free up funds for taxpayers and encourage officeholders to take up private jobs or start businesses, making them productive members of society.
