Allow me to point out my perspective. I'm a Duchtman and I'd welcome an Brexit because both the UK with it's City of London and the EU are both agents of a global perversion of capitalism. I'm very Europe minded, but the EU's claim of the whole continent's successes as their own seem right wing populist to me. Populism is not exclusive to xenofobic parties. Most of what makes Europe great is the product of sovereign democratic nations in it cooperating peacefully. The EU's predecessors like the EC and the EEC were part of that cooperation, this EU is the enemy of democracy and therefore the acquired wealth or what's left of it like decent working hours, vacations, wages that easily pay rents, food safety, security, health care, environmental care etc. They are the product of democracy, not of international cooperation and the EU is turning back the clock as is the Anglo Saxon model of reaganomics and Thatcherism.
But without the UK, the EU might get a bit better because we don't have a powerful country in it which economy is dependent on the City, which is a parasitic and dangerous industry. That could make it possible for the EU to finally clean up and shrink down the financial sector. That's why the US, i.e. Wall Street loyals like the Clintons and Obama, need the UK to stay in the EU so badly. And that's why I want you English out, the rest of the UK can come back in.
