A second source of concern is that free trade encourages firms from advanced nation to move manufacturing facilities to less developed countries that lack adequate regulations to protect labor and the environment from abuse by the unscrupulous. Globalization critics often argue that adhering to labor and environmental regulations significantly increases the costs of manufacturing enterprises and puts them at a competitive disadvantage in the global marketplace visa-vis firms based in developing nations that do not have to comply with such regulations. Firms deal with this cost disadvantage, the theory goes, by moving their production facilities to nations that do not have such burdensome regulations or that fail to enforce the regulations they have.
If this were the case, one might expect free trade to lead on an increase in pollution and result in firms from advanced nations exploiting the labor of less developed nations. This argument was used repeatedly by those who opposed the 1994 formation of the North American Free Trade Agreement (NAFTA) between Canada, Mexico, and the United States. They painted a picture of U.S. manufacturing firms moving to Mexico in droves so that they would be free to pollute the environment, employ child labor, and ignore workplace safety and health issues, all in the name of higher profits.
Supporters of free trade and greater globalization express doubts about this scenario. They argue that tougher environmental regulations and stricter labor standards go hand in hand with economic progress. In general, as countries get richer, they enact tougher environmental and labor regulations. Because free trade enables developing countries to increase their economic growth rates and become richer, this should lead to tougher environmental and labor laws. By creating wealth and incentives for enterprises to produce technological innovations, the free market system and free trade could make it easier for the world to cope with pollution and population growth.
Factually, pollution levels are rising in the world’s poorer countries, even as they have been falling in developed nations. While this affirms the argument that economic development can foster better environmental conditions, it does not address the whole global picture, particularly the situation in emerging economies.
