tomdesigns, I can surely appreciate your sentiment. It can be hard to rationlize the poverty here sometimes (though it doesn't compare with what I witnessed in India). With all compassion for your feelings I'm not sure "crippled" is a word that I would use.
We had a housekeeper for years from Paraguay. She spoke Guaraní, the language you were probably referring to, and Spanish. The level of poverty from which she came was unbelievable. And the stories she would tell of what they had to do to get (almost) edible food would make you squirm.
She lived in the villa next to Retiro when my wife met her on the street in front of our apartment. She offered to sweep the sidewalk every morning for 2 pesos. We paid her for a week. Then we noticed that she was not only sweeping the sidewalk but had brought a couple of guys with her one morning to fix a broken tile in the sidewalk. In addition, she was watering the plants and flowers, and she re-hung a welcome sign that had blown off the door.
We helped her get her papers and hired her as our nanny. She was unbelievably great: responsible, dedicated, and always did 50% more than what you asked her to do. And, for someone with a 3rd grade education, she was suprisingly astute about politics and how the world works. She was very aware that (many) governments "buy" votes by giving freebies. Once she was able to vote, she voted her conscience.
There are many stories like this that friends here have relayed to me. What I've taken from my 47 year's experience with people is that education level, socio-economic level, race, nationality, religion, etc, do not determine a person's honesty, clarity of thought, and compassion for one another.
Having said all of that, though I may feel horrible about the conditions in which others in the world might be living, I can't be responsible for the entire world. What I can do is help when and where given my means and ability. Take comfort in the fact that you can, and do, make a positive difference with the people that you meet every day in your own way. To those people that difference can be extraordinary.
