North American Free Trade Agreement (NAFTA) -
Basically the purpose of NAFTA does not have much to do with promoting economic trade itself even though it's named beautifully free trade agreement. The real focus of NAFTA is to supress wages of labour and exploit markets in the three north American countries for the gains of big corporations at expenses of average folks.
20 years after NAFTA, the disastrous results for working people in the three countries showed up, particularly for the middle class.
