This does not just apply in India. A long time ago, I had a job soliciting donations door to door in the US. We did all we could to avoid the rich neighborhoods and actively sought out the poor minority neighborhoods. People in those neighborhoods with only two dollars would give one to help others. In the rich neighborhoods, they would call the police the moment they saw you. If I ever had to have a heart attack in the street, I would much rather have it in a poor neighborhood, because some kind person would help me.

My theory is that poor people rely on cooperation with others to survive, and this forces them to develop compassion and learn good human relations at a young age. Rich people on the other had don't need others so much, and instead are much likely be in competition with them.

Even in family relations this applies. Siblings in poor families offer much needed support to each other. In rich families siblings seem more likely to be considered as competitors for parental affections at a young age, and competitors for inheritance when older. This mentality of constant competition is poisonous.

Honestly, I think that being rich is a pretty clear path to ultimate unhappiness. Better to be slightly poor in money and rich in the things that actually bring happiness, like family, health, friends, spare time, and a clear conscience.
