NAFTA is the North American Free Trade Agreement signed in 1994 by Canada, USA and Mexico, this allowed a free-trade zone between the three countries, this meant that there would be little to no taxes for products being produced and sold in these three countries, exports and imports would not be or would be small taxed, and the biggest fear was that American companies would go to Mexico because of the lower wages and less enviromental controls, making their products cheaper increasing profit.
