The Leave-Remain compaign was never about sovereignity, it was always about xenophobia, pure and simple. For a tolerant country like the UK, founded on immigration and international empire, this xenophobia does not come naturally. Xenophobia was only a fringe movement on the right until the Tories decided to co-opt the language of racism in order to gain an electoral advantage over Labour. They thought they could repeat UKIP and BNP talking points against immigrants and the EU in order to pick up extra votes. It worked, but they legitimised a monster which has just proven willing to trash the UK economy in order to kick out Polish plumbers. If the Tories had had the moral courage to speak out against xenophobia early and strong, this would never had happened.
So what is gained by Brexit? Basically nothing. What the leave campaign didn't tell you is that the UK only voted against 2% of EU laws, so 98% of EU laws were put in place with the support of the UK government. All EU laws and regulations require the support of either elected governments or elected MEPs, so the UK still had a say over every decision made. Now it won't have a say, but it will have to abide by all of the laws and regulations anyway if it wants access to its largest trading partner. Bravo Leave campaign, you have just reduced the sovereignity of the UK. And if the UK decides not to be part of the EU trading block? Well the British pound instantly dropped 11% on this possibility, so get ready for a slow flight of capital out of the UK and into the US or Europe.
How about immigration? Again, it is disingenuous (i.e., a lie) to say that the UK lost control over its borders to the EU. The UK government was one of the leaders in the push to expand the EU to the east, and when Eastern Europe joined each EU member state was given the possibility to delay free migration. The UK was one of those countries that allowed immediate immigration - as a choice of the UK government. The simple fact is, the high level of immigration to the UK has nothing to do with the EU. It is driven by history, empire lost and the deliberate choice of the UK government to put economic growth over racial purity. So what will happen now? Well a bunch of Brits will lose their jobs in the EU, British retirees won't find it so easy to swan around in southern Spain, and French and German professionals will be discourged from working in London. That's it. The UK will still be a country of immigrants (sorry racists), and the only impact Brexit will have on slowing that process is if the economy collapses so badly that immigrants don't want to come any more.
What a disaster.
