Financial Times journalist Simon Kuper's book Chums: How a Tiny Caste of Oxford Tories Took Over the UK argues that in order to understand how power works in the UK, you have to examine Oxford University, where most of its prime ministers are educated. The university has long functioned as the springboard to power for aspiring UK politicians, and Kuper takes us inside this insidious clubhouse, delivering a "searing critique of the British ruling class." Kuper argues that Brexit, far from being a "populist" revolt, would not have been possible without Oxford-educated Tory elites who were in search of a grand political project. Kuper discusses the disturbingly reactionary culture of the Oxford that nurtured Boris Johnson (as well as its low intellectual standards), and explains why—although certain improvements have been made—he believes the university should stop teaching undergrads altogether in order to diversity the pool of backgrounds of those who end up in British politics. 

The clip at the beginning is taken from the 1981 Granada Television adaptation of Brideshead Revisited, which Kuper says many Oxford students in Thatcher-era Britain watched and consciously tried to emulate.
