"the detail needs to be considered and discussed when discussing Brexit"
Therein lies the problem. So not before the vote then. Afterwards is fine, when the poor that voted brexit did not realise just how much poorer they were going to be
I think this highlights one of the really bizarre aspects of the whole referendum campaign and aftermath. All these things should have been bring discussed before the referendum. But to some extent discussion was a politics free zone. The Labour party (who I think have tied themselves in mental knots in the last few years) were not really discussing the actual situation of working class people. They seemed to buy into the whole "one economy", "all in this together" narrative for the purposes of the campaign.
Neither Labour or the Tories were able to discuss any of the real causes of discontent because these are either
a) the fault of successive governments (underfunding of the NHS, housing policy etc) or
b) related to being in the EU (high immigration of unskilled labour with the negative effects on jobs, services, housing, all on the least well off and the benefits to the well off).
So instead all the talk was of one economy. People's actual standard of living is so much more complex than just GDP etc. For example, our country is now much wealthier than 20/30 years ago but buying a house (which to me is fairly basic human requirement in this society) is beyond the reach of many. How is that being better off?
And I am not saying that Brexit will solve all these problems. It will solve some, but not all. I think the issue of inequality is a huge problem which needs to be tackled and it makes me very sad that at the moment we don't seem to have a Labour party who are minded or able to do so.
