Complete text of Greenspan testimony

Beyond the near term, benefits promised to a burgeoning retirement-age population under mandatory entitlement programs, most notably Social Security and Medicare, threaten to strain the resources of the working-age population in the years ahead. Real progress on these issues will unavoidably entail many difficult choices. But the demographics are inexorable, and call for action before the leading edge of baby boomer retirement becomes evident in 2008. This is especially the case because longer-term problems, if not addressed, could begin to affect longer-dated debt issues, the value of which is based partly on expectations of developments many years in the future.

Another critical long-run economic challenge facing the United States is the need to ensure that our workforce is equipped with the requisite skills to compete effectively in an environment of rapid technological progress and global competition. Technological advance is continually altering the shape, nature, and complexity of our economic processes. But technology and, more recently, competition from abroad have grown to a point at which demand for the least-skilled workers in the United States and other developed countries is diminishing, placing downward pressure on their wages. These workers will need to acquire the skills required to compete effectively for the new jobs that our economy will create.

At the risk of some oversimplification, if the skill composition of our workforce meshed fully with the needs of our increasingly complex capital stock, wage-skill differentials would be stable, and percentage changes in wage rates would be the same for all job grades. But for the past twenty years, the supply of skilled, particularly highly skilled, workers has failed to keep up with a persistent rise in the demand for such skills. Conversely, the demand for lesser-skilled workers has declined, especially in response to growing international competition. The failure of our society to enhance the skills of a significant segment of our workforce has left a disproportionate share with lesser skills. The effect, of course, is to widen the wage gap between the skilled and the lesser skilled.

In a democratic society, such a stark bifurcation of wealth and income trends among large segments of the population can fuel resentment and political polarization. These social developments can lead to political clashes and misguided economic policies that work to the detriment of the economy and society as a whole. As I have noted on previous occasions, strengthening elementary and secondary schooling in the United States--especially in the core disciplines of math, science, and written and verbal communications--is one crucial element in avoiding such outcomes. We need to reduce the relative excess of lesser-skilled workers and enhance the number of skilled workers by expediting the acquisition of skills by all students, both through formal education and on-the-job training.

Although the long-run challenges confronting the U.S. economy are significant, I fully anticipate that they will ultimately be met and resolved. In recent decades our nation has demonstrated remarkable resilience and flexibility when tested by events, and we have every reason to be confident that it will weather future challenges as well. For our part, the Federal Reserve will pursue its statutory objectives of price stability and maximum sustainable employment--the latter of which we have learned can best be achieved in the long run by maintaining price stability. This is the surest contribution that the Federal Reserve can make in fostering the economic prosperity and well-being of our nation and its people.
