Caste

This is a well organized exploration of its topic, but even as someone who has only read a little bit about the history of racism and oppression in America, this book was still full of stories I have already heard (the schoolteacher's experiment of segregating her class by eye colour, Albert Einstein's allyship with the black community, etc).

Still though, this is obviously an important issue and the main thesis of the book is interesting: Racism is a byproduct of the caste system, not the other way around. The upper caste stays ahead of others by discrediting them, and discrediting people individually is difficult, so the easiest thing to do is to discredit an entire group based on a visible difference.
