Yeah, the subject matter was so infuriating... Looking back, I think the parts that still stuck with me were the relationship that these businesses would have with the government and how regulatory capture would end up happening, as well as how large corporations' tactics have changed over time, like with the charitable donations to universities.

Also, I haven't watched Succession, but I imagine the drama between different branches of the Sackler family is kinda like what happens in the show, and that was a pretty entertaining part of the book! Have you watched it?
