There can be no doubt, writes economist Melvyn Krauss, that the prosperity of the industrial nations since the Second World War has been due largely to global specialization and interdependence. No one country does all tasks today -- products are designed in one country, produced in another and assembled in a third. The increased standard of living resulting from global specialization in turn has led to the growth of the modern welfare state, including an increased demand for economic security and social measures which guarantee politically-determined minimum consumption standards for citizens. Ironically, says Krauss, as the debate over the North American Free Trade Area (NAFTA), the General Agreement of Tariffs and Trade (GATT) and the recently established World Trade Organization demonstrate, today's welfare state has evolved into a protectionist state. U.S. consumer advocates (Ralph Nader) see free trade as a threat to consumerist legislation. U.S. environmentalists (Jerry Brown) see free trade as a threat to environmental legislation. U.S. human rights advocates (Anna Quindlin) see free trade as a threat to human rights abroad. InHow Nations Grow Rich, Krauss argues there is no inherent reason why the growth of the welfare state in the Western industrial countries should conflict with free trade that is, there is no inherent reason for the welfare state to be protectionist. Exposing fallacious welfare state arguments for protection, Krauss makes a powerful case for free trade in general, and NAFTA in particular, as mechanisms for raising U.S. living standards. Americans are made better off through a reallocation of U.S. productive resources from lower-to-higher productivity uses--from textiles to computers, for example. Moreover, by raising wages in Mexico relative to the U.S., Krauss expects NAFTA to help reduce both legal and illegal immigration.
