We Had Our Perestroika. It's High Time for Yours.

The current global crisis demonstrates that the leaders of major powers, particularly the United States, had missed the signals that called for a perestroika. The result is a crisis that is not just financial and economic. It is political, too.

The model that emerged during the final decades of the 20th century has turned out to be unsustainable. It was based on a drive for super-profits and hyper-consumption for a few, on unrestrained exploitation of resources and on social and environmental irresponsibility.

But if all the proposed solutions and action now come down to a mere rebranding of the old system, we are bound to see another, perhaps even greater upheaval down the road. The current model does not need adjusting; it needs replacing. I have no ready-made prescriptions. But I am convinced that a new model will emerge, one that will emphasize public needs and public goods, such as a cleaner environment, well-functioning infrastructure and public transportation, sound education and health systems and affordable housing.

Elements of such a model already exist in some countries. Having rejected the tutorials of the International Monetary Fund, countries such as Malaysia and Brazil have achieved impressive rates of economic growth. China and India have pulled hundreds of millions of people out of poverty. By mobilizing state resources, France has built a system of high-speed railways, while Canada provides free health care. Among the new democracies, Slovenia and Slovakia have been able to mitigate the social consequences of market reforms.

The time has come for "creative construction," for striking the right balance between the government and the market, for integrating social and environmental factors and demilitarizing the economy.

Washington will have to play a special role in this new perestroika, not just because the United States wields great economic, political and military power in today's global world, but because America was the main architect, and America's elite the main beneficiary, of the current world economic model. That model is now cracking and will, sooner or later, be replaced. That will be a complex and painful process for everyone, including the United States.

However different the problems that the Soviet Union confronted during our perestroika and the challenges now facing the United States, the need for new thinking makes these two eras similar. In our time, we faced up to the main tasks of putting an end to the division of the world, winding down the nuclear arms race and defusing conflicts. We will cope with the new global challenges as well, but only if everyone understands the need for real, cardinal change -- for a global perestroika.
