Three proponents of our interconnected global markets sound off on the possibilities and pitfalls of the brave new economic world we all share. Daniel Griswold is Director of the Center for Trade and Policy Studies at conservative think tank The Cato Institute. "Offshoring is having a profoundly positive effect on the US economy," he says. "It raises the productivity of society overall, gives us new opportunities for production, as consumers, and raises our overall standard of living. And it also builds connections with people in other countries, kind of knitting the world together in a community of work." Catherine Mann, an economist at the non-partisan Institute for International Economics, is the author of a well-known study on IT offshoring. "Offshoring does not abandon US interests," she says. "There are many benefits to the US economy, to US workers and US businesses that come from being able to fragment the production process." Robert Reich served as Secretary of Labor under President Bill Clinton. He is now a Professor of Public Policy at UC Berkeley and has published numerous books, notably "The Work Of Nations." "If you have a college degree, you are on an upward escalator," he says. "Now it's true, you're not going to have much job security, and if you're worried about job security, sorry. This is a different economy, a different world, a different technological universe. You're going to have to change jobs and change skills and you're going to have to maneuver and navigate in ways that may be uncomfortable."
