Globalization - the almost instantaneous movement across borders of ideas, technologies, capital and goods - is a tremendous creator of wealth. But more than a decade after new technologies and the Cold War's end started driving modern global economic integration, it's not clear the process is also a good distributor of wealth.
Indeed, there's plenty of evidence that the growing wealth disparities in countries from Latin America to Asia are attributable in part to the divide between those with the capacity to board the globalization train and those left stranded by it.
