Why You Want a Progressive to Be Running the Economy

By Joseph Stiglitz, The Guardian. Posted August 11, 2008.

Both the left and the right say they stand for economic growth. So should voters trying to decide between the two simply look at it as a matter of choosing alternative management teams?

If only matters were so easy! Part of the problem concerns the role of luck. America's economy was blessed in the 1990s with low energy prices, a high pace of innovation, and a China increasingly offering high-quality goods at decreasing prices, all of which combined to produce low inflation and rapid growth.

President Clinton and then-chairman of the US Federal Reserve, Alan Greenspan, deserve little credit for this--though, to be sure, bad policies could have messed things up. By contrast, the problems faced today --high energy and food prices and a crumbling financial system --have, to a large extent, been brought about by bad policies.

There are, indeed, big differences in growth strategies, which make different outcomes highly likely. The first difference concerns how growth itself is conceived. Growth is not just a matter of increasing GDP. It must be sustainable: growth based on environmental degradation, a debt-financed consumption binge, or the exploitation of scarce natural resources, without reinvesting the proceeds, is not sustainable.

Growth also must be inclusive; at least a majority of citizens must benefit. Trickle-down economics does not work: an increase in GDP can actually leave most citizens worse off. America's recent growth was neither economically sustainable nor inclusive. Most Americans are worse off today than they were seven years ago.

But there need not be a trade-off between inequality and growth. Governments can enhance growth by increasing inclusiveness. A country's most valuable resource is its people. So it is essential to ensure that everyone can live up to their potential, which requires educational opportunities for all.

A modern economy also requires risk-taking. Individuals are more willing to take risks if there is a good safety net. If not, citizens may demand protection from foreign competition. Social protection is more efficient than protectionism.

Failures to promote social solidarity can have other costs, not the least of which are the social and private expenditures required to protect property and incarcerate criminals. It is estimated that within a few years, America will have more people working in the security business than in education. A year in prison can cost more than a year at Harvard. The cost of incarcerating two million Americans -- one of the highest per capita rates (pdf) in the world -- should be viewed as a subtraction from GDP, yet it is added on.

A second major difference between left and right concerns the role of the state in promoting development. The left understands that the government's role in providing infrastructure and education, developing technology, and even acting as an entrepreneur is vital. Government laid the foundations of the internet and the modern biotechnology revolutions. In the 19th century, research at America's government-supported universities provided the basis for the agricultural revolution. Government then brought these advances to millions of American farmers. Small business loans have been pivotal in creating not only new businesses, but whole new industries.
