Not just plebs -- toffs are also to blame

The Graun renews its attack on those above as well as those below in its classic petit-bourgeois class politics with this:

Britain’s Brexit crisis is rooted in the power of our public schools

[the ERG is a] 90-strong band of ideologues...Jacob Rees-Mogg. This one-man embodiment of the mess into which we have all been dragged...Where did he come from, this human museum piece?...[His dad William was an Editor of the Times but] the roots of the Rees-Mogg family wealth [are]  in the ownership of coalmines in Somerset....places replete with the ghosts of a lost industrial past and the consequences of the austerity that he has enthusiastically endorsed....His apparent skill in matters of high finance – which, according to a recent edition of Channel 4’s Dispatches, has earned him an estimated £7m since the referendum, assisted by the fall in the value of the pound – goes back to childhood dealing of stocks and shares, and time spent in Hong Kong and the City....

But above all, Rees-Mogg is an old Etonian. Let's discuss the role of this school calmly and rationally:

Eton College. This institution sits at the heart of the Brexit mess and the dismal political failings that led to it. What comes to mind at the mention of Eton? Tailcoats? The eternally mysterious wall game? Or the angry lament contained in the Jam’s Eton Rifles, with its Larkin-esque opening line: “Sup up your beer, and collect your fags / There’s a row going on, down near Slough”, that lyrical portrait of a working class serially defeated by privilege...Eton chiefly symbolises the unbroken English link between private education and power. [For evidence? ] To quote one old boy, who did his time in the 1980s: “Kids arrived there with this extraordinary sense that they knew they were going to run the country.”

Etonians and the alumni of other “top” private schools are still at the core of British rightwing politics. Their fingerprints are all over Brexit. David Cameron was deluded enough to call the referendum in the first place, blithely ignoring the possibility that the cruelties of his austerity programme would inform the public’s response....Thanks to his brazen embrace of a cause he thought would smooth his passage to the Tory leadership, Cameron’s Eton contemporary Boris Johnson led the push to exit the EU

There are books to push as well though:

It is no accident [!!] that, as the scale of the Brexit disaster has grown, two high-profile books – David Kynaston and Francis Green’s Engines of Privilege, and Robert Verkaik’s Posh Boys – have been published tracing the history of so-called public schools and their domination of our power structures.

Generalising a bit, perhaps for 'balance' and perhaps because the upper class enemy is everywhere:

The past three years of British history have proved that privilege often breeds a dangerous mixture of ineptitude and arrogance, as well as incubating the kind of unhinged ideas that could appeal only to people removed from ordinary life, who tend to see the world in terms of crass abstractions. This, incidentally, is something proved by any number of posh revolutionaries, and is evident on the modern political left as well as the right....Brexit should focus minds on how we begin to cut the ties that bind the state, politics and key professions – including journalism – to a tiny number of schools.

However, as we might expect from liberals and their petit-bourgeois clientele:

There is no need to abolish private education. [Heaven forbid! That would make the housing market even more important in picking 'good' state schools]  The simplest solution might prompt outrage, but would be no more drastic than Brexit itself. As well as an end to private schools’ charitable status, it should be demanded, via legislation, that over the next 10 years or so Russell Group universities [so that is the beef?] allocate their places in line with the balance between private and state schools in the population at large, so that 93% of their students are eventually state-educated.

Anticipating some mild protest from his pubic school colleagues as well as from Graun readers?

obviously, it is more than possible to go to Eton, or Harrow, or any number of other fee-paying schools, and emerge as humble, sensitive and self-aware as anyone else. I have also met people profoundly damaged by the experience of private school, even when everything has gone to plan.

Finally, according to Google, J. Harris (the author) was educated at Loreto College and  The Queen's College, Oxford
