A few years ago, at a party hosted by an Indian in the New York suburbs, I chatted with the wife of a senior executive of a major American financial services company who is an IIT graduate. Both husband and wife are from Haryana. I asked if they knew a consultant with a major firm, an IIM graduate who is also from Haryana. She said “We meet at such parties. But we do not socialize. He is a Jat while we are Kayasths.”
