I’ll second this - I was born in India and moved to US at young age. Never had caste come up ever with my family or relatives, but the only time I had to think about it was when someone asked me about it (out of curiosity, not in any other way).

Lately, I picked up one of the introductory courses from Audible - “Great World Religions: Hinduism from The Great Courses”. It was well put together - a whole chapter dedicated to caste system in India. Particularly talks about restriction of mobility and exceptions when it can happen. Highly recommend it for anyone who wants to learn more about the good, the bad and the ugly of Hinduism.

Apparently, I was born in the artisanal caste of India, specifically Blacksmiths: https://en.wikipedia.org/wiki/Panchal
