Documentaries that you think people with responsibility should watch

A question: what documentaries do you think those in power/who are responsible should watch? What should they know about? What should they know before making decisions that would influence whatever they're responsible for?

Answer as you like, I'm curious as to know what you think!

I'll start with two:
'Demain'

'97 percent owned' (I haven't actually seen this but am 95 percent sure I know what it's about and that it's a worthy cause)

Watch the Roger Stone one on Netflix damn interesting,
