Many of our society’s most cherished traditions are actually based on historical accident, the proﬁt motives of a few companies, or the agenda of someone who died long ago. A lot of what we believe and do is bullshit, yet we walk around thinking our way of doing things is inherently correct. Why do we exchange diamond engagement rings? Why is wine so expensive? How does art become “art”? Why do so many non-proﬁts want us to donate cars to them? Why does college cost so much? Why do so many pets die in animal shelters? Why is the world the way it is? Everything is Bullshit, by Priceonomics, is an investigation to ﬁnd the answers.
