From Robert Samuelson, a quote:
Today's global economy baffles experts -- corporate executives, bankers, economists -- as much as ordinary people. Countries are growing economically more interdependent and politically more nationalistic. This is a combustible combination. The old global economy had few power centers (the United States, Europe, Japan), was defined mainly by trade and was committed to the dollar as the central currency. Its major countries shared democratic values and alliances. Today's global economy has many power centers (including China, Saudi Arabia and Russia), is also defined by finance and is exploring alternative currencies to the dollar. Major trading nations now lack common political values and alliances.
It is no more possible to undo globalization than it was possible, in the 19th century, to undo the Industrial Revolution. But our understanding of international markets, shaped by impersonal economic forces and explicit political decisions, is poor.
