with the Latin American governments' interest in shifting national economies toward businesses in which they could use their comparative advantages: abundant natural resources and manual labor, low wages, and low operational costs (CEPAL 2002). As a result of trade liberalization, which is the main purpose of structural adjustments, traditional agriculture was severely affected. Traditional agriculture, the activity in which peasants were mostly involved in Latin America before the 80s, was exposed to global markets by an intensified export thrust and an inundation of imports from countries that often provide generous agricultural subsidies to farming sectors. This trend provoked an asymmetrical competition among agriculture goods produced by non- developed and developed countries, the latter being benefited by the exchange. Due to subsidies still applied in many cases, processed and non-processed agriculture products from rich countries were less expensive than those from poor countries. In addition, the costs of transport, seeds, pesticides, nutrients, and other imported products used in agriculture by peasants were increased due to devaluation of national currencies and new terms of international trade. The consequence of this situation is that peasants of poor countries could not pay these costs, and thus, they were displaced from their habitual agriculture activities. This tendency explains why peasants have had to move from subsistence agriculture to waged work, usually in industrial agricultural plantations, and even to sell their lands for these activities. Another purpose of trade liberalization was the deregulation / liberalization of labor and capital markets. To allow the flow of capital as foreign investment, countries were prompted to reduce or even eliminate some labor benefits traditionally scheduled for workers such as work security, fixed wages and work time, etc. Controlling these factors,
