Anthropology, Class 19 NAFTA, Migration, and Suffering (“Sufrimiento”) Myths and Realities about Migration - Stephen Colbert testifies in House of Reps - They’d be doing the work anyway, so why isn’t it regulated and why aren’t visas granted - The fact that these workers are so inherently important to the structure of our society are being pushed out of the states, while they are still so needed - Nation of immigrants is stopping immigration NAFTA - North American Free Trade Agreement - Went into effect Jan 1, 1994 - Liberalized trade, goal of eliminating barriers to trade and investment between three nations (Mexico, USA, Canada) - Significant political-economic impacts, bad particularly for Mexico, good for USA - It has been opposed and resisted since the day it went into effect- women resistance fighters in Chiapas - Set the blueprint for other trade agreements that have been passed - caused huge dramatic change in migration - David Bacon essay “Globalization and NAFTA Caused Migration from Mexico” • Promise of NAFTA: bring Mexico to “first-world” level, create new jobs/employment/ income across the three countries • Did the opposite: Wage of workers plummeted and profits of companies skyrocketed; corn producers in Mexico were forced to migrate due to extremely low prices of corn from US companies- they couldn’t compete with the low prices, and therefore couldn’t make profit; Pork producers from Mexico had to shut down farms, one farm losing 120,000 jobs due to influx of US pork imports • Changed livelihoods in Mexico and the USA: More migration to the US, inability to make a living in Mexico as a farmer due to monopolization of US companies, US companies profit immensely, displacement of families and communities (kinship relationship are dwindling because those who are at an age to produce families have to migrate) • “Immigrant” doesn’t recognize the workers’ existences before they left Mexico; “Migrant” takes into account the migration process as well as people’s communities of origin and that of the place they travel to find work; “Displacement” in unmentioned in Washington discourse, does not take into account the uprooting of livelihoods in Mexican communities as a result of NAFTA • Government subsidies: huge grants/ gifts of money from the government to companies/ large-scale farms that bring down the price of production, so that product can be sold at a very low price, causing monopolization of the market and therefore HUGE profit How is NAFTA related to suffering - “The economic situation in the Triqui zone… unequal economic practices with colonialist roots in Mexico” (Holmes: 91-92) - Discriminatory nature of international policy - historicizing and contextualizing within NATFA and other policies and relations between Mexico and USA Chapter 4 Discussion of Fresh Fruit, Broken Bodies - How does Holmes define suffering How does picking berries affect the bodies of farmworkers How does Holmes relate this to different forms of violence - Who are Abelino and Crescencio How does Holmes describe their suffering and the health problems they experience in the US What does Holmes say about the root causes of these kinds of problems - What are some of the health problems that migrant farmworkers face as a whole What kinds of health care and other benefits do they have access to, and which can they not access - **Conjugated oppression** important manifesto of this concept in migrant farm worker situations Anthropology, Class 20 Globalization and the Culture of Capitalism - the case of “Land Grabs” - any large scale acquisition of land for large and it’s resources scale purposes - Ex. Water is a huge resource Land Grabs Video - land= asset to increase profits - land for indigenous people provides a way of being and life • broken identity when split with land of their culture - Colonialism was the beginning of this • Territory and resources used to build empires - resources consumed most usually by those more wealthy/ privileged - economic values assigned to natural resources - social, economic, and environmental problems for people and ecosystem of surrounding affected area - too often, inhabitants are forcefully evicted - destroys income and system of local community, usually without permission/consent of local peoples - sometimes companies trick people with loopholes and language in contracts that the people may not understand the consequences of these loopholes- unknowingly give away their land - contamination of resources (water) - “land lost, people displaced, violation of the territories of Mother Earth” - physical and cultural strength of local peoples
