You're not getting their position. These people are not enfranchised, they lack the financial means, the education and the investment in whatever jobs they endure to give one about the outcome either way. Governments haven't cared about them for decades and if they had, they made an appalling job of doing anything about the problem. That people doing okay in their nice houses and cars are shocked at the apparent nihilism of such individuals is to misunderstand their plight. Some people doing nicely thank you have looked at the debate and found fellow travellers of the Brexit disenfranchised based on ideological concerns. There isn't a single motivation for Brexit or it wouldn't have reached a critical mass to swing the vote.
I suggest you stop putting words into peoples mouths and thoughts into their minds if you cannot understand what is trying to be said.
I do understand their position because I came from it. Born and bred in one of these areas that the government has ignored for decades (but the EU hasn't ignored). I am not shocked they voted to leave at all. I expected it.
However what I am saying is that even though some of these people think they have nothing to lose, even though some think that by voting to leave they are giving the middle finger to those "people doing okay in their nice houses and cars", leaving the EU has a very real possibility of harming those at the bottom who voted for Brexit more than it will hurt anyone else
And of course I don't think Brexit won because one reason. But I think you can't ignore any of the many reasons either (because the difference in the result was so small, you take out one reason and it is easily likely remain would have won).
