Global corporations are increasingly decentralized and willing to manufacture, design or assign managerial authority wherever they can best serve the customer, irrespective of government interests. There is now as much intranational competition as international competition. Cities and regions within the same county compete against each other to attract investment, both from domestic and from foreign sources.
Only a global regionalism that ignores national boundaries makes sense. Local communities develop natural partners, whether geographically close or remote, and prosper to the extent that they are alert.
