I would go by something like:

"The industrial society and its future" - Theodor Kaczinski.

"The communist manifesto" - Karl Marx.

"Rules for Radicals" - Saul Alinsky

"Hitler's War" - David Irving

"The Souls of Black Folk" - W.E.B. Du Bois

"Capital in the Twenty-First Century" - Tom Pickety

"Las venas abiertas da America Latina" - Eduardo Galeano

"The question of Palestine" - Edward Said.

"Grapes of Wrath" - John Steinbeck.

"The conquest of Bread" - Kropotkin

"Problems of Leninism" - Josef Stalin

If adventurous, I'd cite another one I've read that should not be mentioned amongst educated XXI century folks, as they think reading a book means you agree with the author.

Not the last 10 books I've read, but books I've read along my life and that would maybe make the guy think twice before considering making me an offer.
