...Sounds depressing.
What did you get out of it? Gratitude that your life isn't as terrible as theirs?
Now this will sounds trite but this work is "a testimony to the beauty of the human spirit." :) yes, I know, roll you eyes.
In reality, I love India and read a fair number of novels set in India because the place fascinates me. I love reading about the culture, food, fabrics, and architecture. Part of my fascination is with the incredible disparity of life there, and what that huge population of underclass do every day to stay alive and the conditions in which they live.
This particular novelist was good at presenting these four main characters as engaging human beings. You do not want to know what one of the men who underwent forced vasectomy goes through.
I'm the only person I know who actually likes receiving telemarketer calls from India, I like to imagine what the caller is experiencing (where he is sitting, what the weather is like, what is the building he's like, etc.)
