Everyone has heard that tackling poverty and inequality is bad for the economy. This is the dilemma that economist Arthur Okun, writing in the 1970s, called "The Big Trade-Off" — equality and efficiency are at odds. Yet more and more research and real-world experience suggest just the opposite. If there is a "Big Trade-Off," it is not between equality and efficiency. It is between policies that enrich the most fortunate and a broader distribution of opportunity that helps all Americans.
The notion of a Big Trade-Off between equality and growth has been a mostly silent but sometimes explicit assumption of Washington policymakers. Today, for example, many argue we don't have the capacity to reduce economic divisions. Instead, we need to immediately slash public spending. Since the 1970s, political leaders have drastically cut tax rates on the wealthiest and deregulated large swaths of the economy, especially finance, in the name of faster growth.
Okun was right on one front: Cutting taxes and deregulating finance do increase inequality. During the expansion of the 2000s, for example, more than half of all household income gains after taxes and benefits accrued to the richest 1 percent of Americans. Today, the U.S. has greater levels of inequality than any peer nation.
What we have not seen, however, is faster growth. Our economy has grown at roughly the same rate as other advanced industrial economies. But unlike other countries in the Organization for Economic Co-operation and Development, our growth has overwhelmingly benefited the well off. Deregulation in the financial sector, meanwhile, contributed to the multiple economic crises that have unfolded since the 1980s, including the financial crisis from which we are still recovering.
Although moderate inequality is inevitable and even desirable in a capitalist economy, there is good reason to believe that today's extreme inequality is at odds with dynamic growth. Even if we discount the moral case for greater equality, the economic case is increasingly compelling.
First, poverty excludes tens of millions of Americans from the mainstream economy. More than 100 million Americans — one third of us — live in or near poverty, struggling every day. Far too many of them never have the opportunities (because of limited assets, a poor education or both) to achieve their potential. According to a report by McKinsey & Co., the gaps in access to education based on income impose the cost of a "permanent national recession." At a time of increasing global competition, this economic marginalization squanders our greatest asset: individual creativity and industriousness.
Nor are these challenges limited to the poorest Americans. Many middle-class families face comparable difficulties paying for housing and health care, attaining a decent education, and establishing savings. This is the second issue: A weaker middle class means a weaker economy. As recent research by International Monetary Fund economists Michael Kumhof and Romain Rancière suggests, higher inequality creates conditions for economic instability. In contrast, a strong middle class encourages stable, robust consumption, and therefore stable, robust demand for domestic goods and services and sustainable growth.
Finally, beyond these direct economic effects, today's hyperconcentration of income threatens our economy through our political system. Economic inequality translates into political inequality. The vast disparities between the rich and the rest have helped the wealthy accrue significant political power, which they can use to turn policy to their advantage. For example, falling effective tax rates on the wealthy have reduced public revenues. With tightened fiscal circumstances has come a sharp decline in public investments in areas like infrastructure and scientific research and development, reducing our economic potential.
Recognition of these three points is almost entirely missing from current U.S. debates. Conventional wisdom holds that we must cut domestic spending to reduce government debt and help grow the economy. But this argument has it backward. The experience of country after country over the last decade has shown that austerity in depressed economies is largely self-defeating, reducing economic performance so sharply that promised fiscal gains fail to materialize.
More important, budget balance alone will not build an economy of broadly shared prosperity. Instead, we need to take advantage of historically low interest rates to make major investments. America's most important deficits today are in our physical, intellectual and human capital — not federal finances. To encourage growth, we need to fix those deficits first. Investments in roads and schools can put millions of Americans back to work and boost our long-term competitiveness. Pre-K education and greater help for college (along with measures to control education costs) will bolster educational achievement, help families invest in their futures, and create the entrepreneurs and skilled workers of tomorrow.
In the long term, of course, stabilizing our national debt is essential and will require both enhanced revenues and reductions in projected spending. But the place to find savings is not in investments but in our exorbitant health spending, which is the key driver of the deficit, and in special deals for industries that impose large costs on our environment or society, such as the fossil fuel and financial sectors.
There is no "Big Trade-Off." America's vast economic divide is not a necessary evil we must tolerate. It is an unnecessary barrier to a stronger economy — one we could break through while also adopting responsible budget policies. Bolstering economic opportunity and security for the many Americans who struggle to get by is not just the right policy, but the best policy for our economy. We must right this wrong.
