A decentralized, open, capitalist economy is needed, open to free internatio nal flow of trade, capital, people and technology. The function of Governments is only to deny mobs and private armies access to physical force and protect the lives and welfare and individual freedom and property of it's citizens, without infringing upon their economic freedom to be productive and creative. Governments are wholly dependent upon individual citizens productivity to support the Government. Privatizing by selling the tools of production out from under citizens is killing the goose that lays the golden egg. Only the use of such tools of production by citizens to produce a GDP can support the government.
Global specialization adds to efficiency.
The pressures of international competition are a superb antidote to the reluctance of monopolies. The more a country opens its borders to global competition, the more it benefits its domestic consumers. Citizens will be hard-pressed to develop a reasonable standard of living, until they engage in international trade. The most valuable cargo of all is a human being. Today's international financial transactions dwarf the volume of goods and services.
