Although the U.S. economy will likely remain the worlds largest national economy for many decades, it is far less certain that U.S. households will continue to enjoy the highest average standard of living among industrialized nations. A number of other nations have rapidly caught up to U.S. levels of income and per capita output over the last five decades of the 20th century. They did this partly by adopting technologies and business practices that were first developed in the United States, or by developing their own technological and managerial innovations. But in large part, these nations have caught up with the United States because of their higher rates of savings and investment, and in some cases, because of their stronger systems for elementary and secondary education and for training of workers.
Most U.S. workers and families will still be better off as the U.S. economy grows, even if some other economies are growing faster and becoming somewhat more prosperous, as measured per capita. Certainly families in Britain today are far better off materially than they were 150 to 200 years ago, when Britain was the largest and wealthiest economy in the world, despite the fact that many other nations have since surpassed the British economy in size and affluence.
A more important problem for the U.S. economy in the next few decades is the unequal distribution of gains from growth in the economy. In recent decades, the wealth created by economic growth has not been as evenly distributed as was the wealth created in earlier periods. Incomes for highly educated and trained workers have risen faster than average, while incomes for workers with low levels of education and training have not increased and have even fallen for some groups of workers, after adjusting for inflation. Other industrialized market economies have also experienced rising disparity between high-income and low-income families, but wages of low-income workers have not actually fallen in real terms in those countries as they have in the United States.
In most industrialized nations, the demand for highly educated and trained workers has risen sharply in recent decades. That happened in part because many kinds of jobs now require higher skill levels, but other factors were also important. New production methods require workers to frequently and rapidly change what they do on the job. They also increase the need for quality products and customer service and the ability of employees to work in teams. Increased levels of competition, including competition from foreign producers, have put a higher premium on producing high quality products.
Several other factors help explain why the relative position of low-income workers has fallen more in the United States than in other industrialized Western nations. The growth of college graduates has slowed in the United States but not in other nations. United States immigration policies have not been as closely tied to job-market requirements as immigration policies in many other nations have been. Also, government assistance programs for low-income families are usually not as generous in the United States as they are in other industrialized nations.
Changes in the make-up of the U.S. population are likely to cause income disparity to grow, at least through the first half of the 21st century. The U.S. population is growing most rapidly among the groups that are most likely to have low incomes and experience some form of discrimination. Children in these groups are less likely to attend college or to receive other educational opportunities that might help them acquire higher-paying jobs.
The U.S. population will also be aging during this period. As people born during the baby boom of 1946 to 1964 reach retirement age, the percentage of the population that is retired will increase sharply, while the percentage that is working will fall. The demand for medical care and long-term care facilities will increase, and the number of people drawing Social Security benefits will rise sharply. That will increase pressure on government budgets. Eventually, taxes to pay for these services will have to be increased, or the level of these services provided by the government will have to be cut back. Neither of those approaches will be politically popular.
A few economists have called for radical changes in the Social Security system to deal with these problems. One suggestion has been to allow workers to save and invest in private retirement accounts rather than pay into Social Security. Thus far, those approaches have not been considered politically feasible or equitable. Current retirees strongly oppose changing the system, as do people who fear that they will lose future benefits from a program they have paid taxes to support all their working lives. Others worry that private accounts will not provide adequate retirement income for low-income workers, or that the government will still be called on to support those who make bad investment choices in their private retirement accounts.
Political and economic events that occur in other parts of the world are felt sooner and more strongly in the United States than ever before, as a result of rising levels of international trade and the unique U.S. position as an economic, military, and political superpower. The 1991 breakup of the Union of Soviet Socialist Republics (USSR)perhaps the most dramatic international event to unfold since World War IIhas presented new opportunities for economic trade and cooperation. But it also has posed new challenges in dealing with the turbulent political and economic situations that exist in many of the independent nations that emerged from the breakup . Some fledgling democracies in Africa are similarly volatile.
Many U.S. firms are eager to sell their products to consumers and firms in these nations, and U.S. banks and other financial institutions are eager to lend funds to support investments in these countries, if they can be reasonably sure that these loans will be repaid. But there are economic risks to doing business in these countries, including inflation, low income levels, high crime rates, and frequent government and company defaults on loans. Also, political upheavals sometimes bring to power leaders who oppose market reforms.
The greater political and economic unification of nations in the European Union (EU) offers different kinds of issues. There is much less risk of inflation, crime, and political upheaval to contend with in this area. On the other hand, there is more competition to face from well-established and technologically sophisticated firms, and more concern that the EU will put trade barriers on products produced in the United States and in other countries that are not members of the Union. Clearly, the United States will be concerned with maintaining its trading position with those nations. It will also look to the EU to act as an ally in settling international policies in political and economic arenas, such as a peace initiative in the Middle East and treaties on international trade and environmental issues.
The United States has other major economic and political interests in the Middle East, Asia, and around the world. China is likely to become an even larger trading partner and an increasingly important political power in the world. Other Asian nations, including Japan, Korea, Indonesia, and the Philippines, are also important trading partners, and in some cases strong political and national security allies, too. The same can be said for Australia and for Canada, which has long been the largest single trading partner for the United States. Mexico and the other nations of Central and South America are, similarly, natural trading partners for the United States, and likely to play an even larger role over the next century in both economic and political affairs.
It may once have been possible for the United States to practice an isolationist policy by developing an economy largely cut off from foreign trade and international relations, but that possibility is no longer feasible, nor is it advisable. Economic and technological developments have made the worlds nations increasingly interdependent.
Greater world trade and cooperation offer an enormous range of mutually beneficial activities. Trading with other countries inevitably increases opportunities for travel and cultural exchange, as well as business opportunities. In a very broad sense, nations that buy and sell goods and services with each other also have a greater stake in other forms of peaceful cooperation, and in seeing other countries prosper and grow.
On the other hand, global interdependence also raises major problemspolitical, economic, and environmentalthat require international solutions. Many of these problems, such as pollution, global warming, and assistance for developing nations, have been cont
