The 4 underlying EU principles do look a lot like a neoliberal wish list, but unlike any other trading block the EU has balanced that with strict protections for its citizens.
The mobility rights might appeal more to the better off, but the protections enshrined in EU law have done far more for the less well off than people realise. It's not just employment rights, its consumer rights, data protection, environmental, food standards, fair(er) banking, all sorts put into UK law because of EU directives. The UK acting alone would never have tidied up the TUPE loopholes that allowed employers to dismiss staff if they sold the business, introduced extended maternity rights, given at least some rights to part time and agency workers, stopped pumping untreated raw sewage into the sea or insisted on traceability of many foods. So when a close relative is fired, or gets pregnant, or finds their employer sold off, or many other things look back to what it would have been like for them 48 years ago. EU directives set out a minimum, countries can do more, just look at maternity rights and pay in Scandinavia, so all the bluster about now we are out we can make things better is just that, cheap soundbite bluster.
Now, I know Johnson and May before him promised to maintain all those things, but the legal obligation to do so was quietly dropped from the withdrawal bill. So now the UK Govt is free to do as it pleases and argue about tariffs afterwards.
Lots of people, particularly those in precarious employment, have to rely on Johnson keeping his promises. He doesn't have a good record.
The EU runs on consensus politics. It takes time but the extremes get weeded out. That is an anathema to our "Britain is best, I have the right to do what I want and do it now" rhetoric around sovereignty. We were better protected and safer in the EU. That was what we lost last night.
I wish I could join those who trust Johnson, Gove, Truss and their cabal to look after our interests, but I can't.
