Major causes for Brexit:
1. Immigration to to take advantage of the socialist welfare state. London is longer British in any meaningful way.
2. EU regulations that gave fishing rights in U.K. waters to foreigners, and many other regulations that hurt U.K. business.
3. Destruction of free speech. British do like to speak freely, and the shut up and take it movement ran into resistance.
But mostly immigration and the resulting crime wave.
Nope. British fishing rights were SOLD by the rich families that owned them. It makes me laugh that the EU gets blamed for everything, when it was our own rich elites that did it in order to get richer.
Britain sold our fish quotas for a quick buck
We can veto any regulations the EU wishes to impose on us.
Boris the Clown has been lying about the EU for years, too. A couple of weeks ago he was waving a kipper around saying that EU regulations require kipper suppliers to keep their products cool with ice pillows when they are delivered. These regulations are the UK's OWN RULES and the EU has nothing to do with them at all. It's a complete farce.
