BadKnee your analysis above was well-expressed and I'm sure such beliefs were why some working-class communities voted Leave. However, the big question is how will leaving the EU help unskilled British workers?
While there may be some reduction in EU immigration, I can't see how unskilled workers will get any pay rise. The impact on schools is about funding -80% taken by immigrants - really??? This smacks of hyperbole. Outside remain-voting London, the vast majority get their preferred primary school.
The Brexit model proposed by key Leavers is ultra-globalisation - zero tariffs which would make Chinese imports even cheaper, decimating what is left of British manufacturing, leaving just more gig economy style jobs. Uber and deliveries may fill the gap for now, but not for long due to self-driving cars - bye bye long-distance lorry driving/taxis etc Farming would be devastated by cheap third-world imports.
In a global world, it will be very hard to be low-skilled and expect a rich-country lifestyle - even with lower immigration - and the UK has far too high a proportion of school leavers without good qualifications for them all to have a comfortable lifestyle. Yet it seems on mumsnet that the worst parental sin is to be 'pushy'. I am from a working-class background and am forever grateful that my mum was pushy.
On the other hand, high skilled jobs will also struggle as the UK loses the selling point of being the main English speaking country in the single market, and also the benefits of being able to access a well-educated global workforce. Whilst so much infrastructure is here, it's not going to go away quickly but tax revenues will be lower than otherwise and so the ability to fund all the welfare state services which insulate the poorest from the worst effects of the free market.
As for blaming the EU for the rise of the Far Right - I presume the EU is to blame for Trump too, or is this just a reflection of the reality which globalisation means for low-skilled workers in the West?
