As it happens, Guardian writer Owen Jones is mostly right in this article: https://www.theguardian.com/commentisfree/2016/jun/24/eu-referendum-working-class-revolt-grieve
"It may not have been the working-class revolt against the political establishment that many of us favoured, but it is undeniable that this result was achieved off the back of furious, alienated working-class votes."
But he is wrong to say: "The growing chasm between the generations has only been deepened." - the thing about young voters is that they eventually become old voters, and as they accumulate assets they will change how they feel about politics.
