I think we're all a little guilty of falling into a culture wars trap with brexit and all this bullshit about EU membership being the best thing that ever happened or conversely a complete waste of time has very adequately distracted comrades who largely agree on a wide range of issues from making any progress, at all, regarding those issues. It is often thoroughly depressing to read this thread.
I think this, excuse the long rambling...
We have engaged in a fairly stupid but not surprising act of self-destruction that has predictably strengthened prevailing capital interests and in doing so, not as the main event, it will have worsened our conditions. I think back to those who said that a brawl between two factions of capital wasn't their fight and I have some sympathy for that but I think we still tangibly lost. I think a lot of it is regrettable, most particularly the concessions and allowances the public have made, the disconnect between actions and consequences, and the unlikeliness of learning anything valuable from the entire experience. Nonetheless it is not that major a change and no major change is forthcoming. What it has done is damaged or removed the thin layer of social benefits that were provided as compensation, so we as individuals are worse off, but those benefits were inversely proportionate to one's position in society, so it is largely true that all this stuff is 'middle class'. I'll come back to that. Either way the great Brexit debacle is now done and whilst it will have hotly debated consequences it's not likely to be seriously reevaluated any time soon.
That said, this whole first bit is in many ways a waste of time because, in the absence of a great disruptor, global capital will, like water, find its level and it would be wholly unsurprising if we ended up fully back in the EU in my lifetime, without ever having any need for vocal Brejoin.
Then there's the culture war which in many ways is independent of Brexit and exists to either consolidate power in itself, or as a distraction from doing so. All of this stuff about worsening conditions for the middle class is a good if not enormously important example of it, as Winot pointed out earlier. There's a distinct absence of structural analysis in favour of identity stereotypes. It ought to matter more whether these things favour structural inequality that manifests in power relationships, like landlordism or exploiting employment, and if they don't then why are we fighting over them? Is 'middle class' in this context just an ability to consume more or live more lavishly under the same system? So what? Are we really in pursuit of the lowest common denominator amongst ourselves before addressing any higher structures?
Britain and particularly England is going to have to come to terms with what it is or perhaps more importantly isn't. I think the short term outlook for this is poor and we are sliding further backwards from an already negative starting point. In the ways that mattered, we were not really beholden to the EU. We should have confronted that the British state chose to do almost all of what it did, and that continues. I think we the English will for some time continue to empower those responsible for our problems - as we have in this entire enterprise - whilst trying to give each other a kicking for it. I think we deluded ourselves that it was an obsessive 'get Brexit done' mentality that sustained our national politics as they are but think time will show that to be false. I think in time this will probably result in something a lot more fash but I don't know what yet. It's hard to see what positives will flow from it any time soon but before we can think about that we need to get our own house in order and stop doing the very opposite of what we said we would do: establishing solidarity and not fighting capital's culture war.
