In every economic system, entrepreneurs and managers bring together natural resources, labor, and technology to produce and distribute goods and services. But the way these different elements are organized and used also reflects a nation's political ideals and its culture.
The United States is often described as a "capitalist" economy, a term coined by 19th-century German economist and social theorist Karl Marx to describe a system in which a small group of people who control large amounts of money, or capital, make the most important economic decisions. Marx contrasted capitalist economies to "socialist" ones, which vest more power in the political system. Marx and his followers believed that capitalist economies concentrate power in the hands of wealthy business people, who aim mainly to maximize profits; socialist economies, on the other hand, would be more likely to feature greater control by government, which tends to put political aims -- a more equal distribution of society's resources, for instance -- ahead of profits.
While those categories, though oversimplified, have elements of truth to them, they are far less relevant today. If the pure capitalism described by Marx ever existed, it has long since disappeared, as governments in the United States and many other countries have intervened in their economies to limit concentrations of power and address many of the social problems associated with unchecked private commercial interests. As a result, the American economy is perhaps better described as a "mixed" economy, with government playing an important role along with private enterprise.
Although Americans often disagree about exactly where to draw the line between their beliefs in both free enterprise and government management, the mixed economy they have developed has been remarkably successful.
Basic Ingredients of the U.S. Economy
The first ingredient of a nation's economic system is its natural resources. The United States is rich in mineral resources and fertile farm soil, and it is blessed with a moderate climate. It also has extensive coastlines on both the Atlantic and Pacific Oceans, as well as on the Gulf of Mexico. Rivers flow from far within the continent, and the Great Lakes -- five large, inland lakes along the U.S. border with Canada -- provide additional shipping access. These extensive waterways have helped shape the country's economic growth over the years and helped bind America's 50 individual states together in a single economic unit.
The second ingredient is labor, which converts natural resources into goods. The number of available workers and, more importantly, their productivity help determine the health of an economy. Throughout its history, the United States has experienced steady growth in the labor force, and that, in turn, has helped fuel almost constant economic expansion. Until shortly after World War I, most workers were immigrants from Europe, their immediate descendants, or African-Americans whose ancestors were brought to the Americas as slaves. In the early years of the 20th century, large numbers of Asians immigrated to the United States, while many Latin American immigrants came in later years.
Although the United States has experienced some periods of high unemployment and other times when labor was in short supply, immigrants tended to come when jobs were plentiful. Often willing to work for somewhat lower wages than acculturated workers, they generally prospered, earning far more than they would have in their native lands. The nation prospered as well, so that the economy grew fast enough to absorb even more newcomers.
The quality of available labor -- how hard people are willing to work and how skilled they are -- is at least as important to a country's economic success as the number of workers. In the early days of the United States, frontier life required hard work, and what is known as the Protestant work ethic reinforced that trait. A strong emphasis on education, including technical and vocational training, also contributed to America's economic success, as did a willingness to experiment and to change.
Labor mobility has likewise been important to the capacity of the American economy to adapt to changing conditions. When immigrants flooded labor markets on the East Coast, many workers moved inland, often to farmland waiting to be tilled. Similarly, economic opportunities in industrial, northern cities attracted black Americans from southern farms in the first half of the 20th century.
Labor-force quality continues to be an important issue. Today, Americans consider "human capital" a key to success in numerous modern, high-technology industries. As a result, government leaders and business officials increasingly stress the importance of education and training to develop workers with the kind of nimble minds and adaptable skills needed in new industries such as computers and telecommunications.
But natural resources and labor account for only part of an economic system. These resources must be organized and directed as efficiently as possible. In the American economy, managers, responding to signals from markets, perform this function. The traditional managerial structure in America is based on a top-down chain of command; authority flows from the chief executive in the boardroom, who makes sure that the entire business runs smoothly and efficiently, through various lower levels of management responsible for coordinating different parts of the enterprise, down to the foreman on the shop floor. Numerous tasks are divided among different divisions and workers. In early 20th-century America, this specialization, or division of labor, was said to reflect "scientific management" based on systematic analysis.
Many enterprises continue to operate with this traditional structure, but others have taken changing views on management. Facing heightened global competition, American businesses are seeking more flexible organization structures, especially in high-technology industries that employ skilled workers and must develop, modify, and even customize products rapidly. Excessive hierarchy and division of labor increasingly are thought to inhibit creativity. As a result, many companies have "flattened" their organizational structures, reduced the number of managers, and delegated more authority to interdisciplinary teams of workers.
Before managers or teams of workers can produce anything, of course, they must be organized into business ventures. In the United States, the corporation has proved to be an effective device for accumulating the funds needed to launch a new business or to expand an existing one. The corporation is a voluntary association of owners, known as stockholders, who form a business enterprise governed by a complex set of rules and customs.
Corporations must have financial resources to acquire the resources they need to produce goods or services. They raise the necessary capital largely by selling stock (ownership shares in their assets) or bonds (long-term loans of money) to insurance companies, banks, pension funds, individuals, and other investors. Some institutions, especially banks, also lend money directly to corporations or other business enterprises. Federal and state governments have developed detailed rules and regulations to ensure the safety and soundness of this financial system and to foster the free flow of information so investors can make well-informed decisions.
The gross domestic product measures the total output of goods and services in a given year. In the United States it has been growing steadily, rising from more than $3.4 trillion in 1983 to around $8.5 trillion by 1998. But while these figures help measure the economy's health, they do not gauge every aspect of national well-being. GDP shows the market value of the goods and services an economy produces, but it does not weigh a nation's quality of life. And some important variables -- personal happiness and security, for instance, or a clean environment and good health -- are entirely beyond its scope.
A Mixed Economy: The Role of the Market
The United States is said to have a mixed economy because privately owned businesses and government both play important roles. Indeed, some of the most enduring debates of American economic history focus on the relative roles of the public and private sectors.
The American free enterprise system emphasizes private ownership. Private businesses produce most goods and services, and almost two-thirds of the nation's total economic output goes to individuals for personal use (the remaining one-third is bought by government and business). The consumer role is so great, in fact, that the nation is sometimes characterized as having a "consumer economy."
This emphasis on private ownership arises, in part, from American beliefs about personal freedom. From the time the nation was created, Americans have feared excessive government power, and they have sought to limit government's authority over individuals -- including its role in the economic realm. In addition, Americans generally believe that an economy characterized by private ownership is likely to operate more efficiently than one with substantial government ownership.
Why? When economic forces are unfettered, Americans believe, supply and demand determine the prices of goods and services. Prices, in turn, tell businesses what to produce; if people want more of a particular good than the economy is producing, the price of the good rises. That catches the attention of new or other companies that, sensing an opportunity to earn profits, start producing more of that good. On the other hand, if people want less of the good, prices fall and less competitive producers either go out of business or start producing different goods. Such a system is called a market economy. A socialist economy, in contrast, is cha
