India is a melting pot of cultures, except that it hasn't melted. India is a diverse mix of cultures. Groups get mad and argue. It would be better if they just got along. For the most part they do. But sometimes they don't. Also, there is much government corruption. People in small towns still care about caste--but the next generation doesn't really care, so there's hope for the future.
This book was a tough slog. As a careful reader, you know to read some things with a grain of salt, and I needed a lot of salt with this book. But there were some good patches.
