The Prince by Niccolo Machiavelli

Famous Book, infamous writer. He was advising rulers how to hold onto powers. Modern day politicians don't need such advice - they come to power with their own natural cunning already in place.
Margaret Thatcher held onto power by sending gun boats to the Falklands; asylum seekers (re-badged as "boat people"by politicians) are trashed in the name of "protecting" us from imagined invasion; and an entire religious community is lumped together as "terrorists".
Politicians create problems for people in order to protect people from those problems and get them selves re-elected. Horrible man, horrible book. 0/5
