I worry there's another global recession coming and within the EU we would be obliged to do so much that our economy would be negatively affected (obviously in a recession everyone suffers but as a main member of the EU I feel it would have disproportionately affected us if we had to bail out Italy for example) I don't want that liability.
I think the EU is on a road to over inflation, don't like what I see as the abuse of power and was worried about what it would mean for the UK if/when the EU builds a super army e.g. is it going to escalate tensions with Russia.
I'm was worried about how we're going to deal with terrorism with the courts being undermined on things like being unable to deport known terrorists. (Again not so bad at the moment but I think in the EU it would get worse)
I quite like having seperate countries with seperate culyures. I don't want to go to Spain, Italy, France and everything has blended into one - this isn't about people it's about culture. I quite like them being seperate but can understand if people feel more comfortable with full integration.
If imigration is cut and more jobs are available then there's more opportunities for our young people. Cutting immigration is likely to relieve pressure on housing and schooling.
I don't see a big super state that the EU is becoming as the way forward, I think it's too risky, I think we're treated badly in the EU and could only see it getting worse. My main driver is having some protection from EU financial issues although I appreciate as I said above we will be impacted somewhat whatever.
In short I think the EU is a bad corrupt institution and not fit for purpose
