[简答题]The biggest problem of the third industrial revolution is as easy to explain as it is difficult to solve. Technology is creating a global economy that is rapidly supplanting our old national economies. National governments cannot control this new economy, yet no one, least of all Americans, wants to create the form of global government that might be able to control it.

National governments, which used to worry about managing and maintaining their economic systems, are slowly being pushed out of business. Changes in global finance overwhelm all but the largest governments. Governments have lost much of their influence over the movement of information and capital. They cannot control who crosses their borders either physically or culturally.
