You foreigners read first few paragraphs of wikipedia article about caste and never stopped talking about it.

In practice most of Brahmins have been peasant agriculturists, teachers and clerics for centuries, and temple priests have been deservedly pretty poor unless they also had inherited land.

The current PM of India is from what is considered as "other backward caste".

Just noting it, so that your overly reductive american journalism won't convince you that India is a feudalist society where 5% "temple staff" rule over the 95% peasants or whatever. The caste system is mostly limited to ritual avtism and some nepotism (which happens among boomers across all castes but younger ones don't care).
