this pretty much sums brexit up:
Rebellion against political consensus
I voted "remain" in the end, but it was a close run thing. I'm philosophical about the results; we won't know the real implications for some time. But be under no illusions, this was not just about the EU. Indeed, the EU never really dominated the campaign. It was a rebellion against a long standing political consensus and, in particular, the legacy of Blairism. In essence, Blairism was the marriage of Thatcherite economics to social mores which had previously been the concern of the far left; basically free markets plus multiculturalism. The intention was that over time, the population would buy into that. In London and Scotland, it more or less happened. But in much of the U.K., the population went the other way. An unbalanced economy dependent on financial services squeezed their finances and living standards, while mass immigration forced down wages and created visible, angry, unassimilated immigrant communities in their midst. Moreover, the usual channels of democratic restoration were blocked. Blair's biggest achievement was to foster a media environment which labelled any questioning of the social consensus as racist and a legal system which in some cases made it an arrestable offence. Meanwhile, too many of our institutions changed their ethos from public service to "thought leadership"; trying to reform the population rather than meeting its needs. The vote, I think, needs to be seen as a rebellion against that. I wish the result had been different, but I accept that it wasn't. I live and work in London and my whole circle voted to remain. My parents live in the suburbs of a northern city and they and their circle voted to leave. I had been warning colleagues for weeks that I thought a Leave win was likely; I thought the polling was both running into "social acceptability bias" and underestimating the likelihood that the lower income groups would vote. This, incidentally, is why I would bet on Trump winning in November, scary though that is. And things feel scary in the UK this morning. But a proper discussion of why the vote went the way it did and an acceptance that we need to at least accept and tolerate our divisions rather than widening them would be good first steps.
