If you have any sense of responsibility at all, stay with your riots here at home. Work for the coming elections: You will know what you are doing, why you are doing it, and how to communicate with those to whom you speak. And you will know when you fail. If you insist on working with the poor, if this is your vocation, then at least work among the poor who can tell you to go to hell. It is incredibly unfair for you to impose yourselves on a village where you are so linguistically deaf and dumb that you don't even understand what you are doing, or what people think of you. And it is profoundly damaging to yourselves when you define something that you want to do as "good," a "sacrifice" and "help."
I am here to suggest that you voluntarily renounce exercising the power which being an American gives you. I am here to entreat you to freely, consciously and humbly give up the legal right you have to impose your benevolence on Mexico. I am here to challenge you to recognize your inability, your powerlessness and your incapacity to do the "good" which you intended to do.
I am here to entreat you to use your money, your status and your education to travel in Latin America. Come to look, come to climb our mountains, to enjoy our flowers. Come to study. But do not come to help.
Ivan Illich, from To Hell with Good Intentions. 1968.
