I really like reading international economics and politics from the 60s and 70s. You realize that a lot of non fiction gets recycled often, and the no-nonsense analysis they did back then gets watered down a lot with the current touchiness of talking about different cultures. There was a lot of bias back then too, to be sure... But comparing different biases is the best way to filter some of them out.
