There is seldom running water or sewage systems. Roads are seldom paved. Workers houses are usually made of scavenged materials - pallets, cardboard, tarps, and often have dirt floors. Wages are as low as the equivalent of 15 cents per hour in countries like Indonesia, China, and Haiti. Workers in Mexico's maquiladora factories receive from about 50 to 90 cents per hour.
Some skilled workers get more.
The supposedly internationally-recognized rights of workers to freely organize and join trade unions of their own choice is almost universally denied in these free trade zones. Workers who try to organize independent unions are routinely fired and blacklisted. The United States government, using our tax dollars, has actively encouraged U.S. companies to move their factories out of the United States. The practice continued into the early years of the Clinton Administration. Toxic dumping by companies operating in free trade zones is also common.
