I can see how that benefits the less wealthy countries in the EU, but I really don’t see how it benefits the UK, especially as we have a different currency and are not landlocked.
On each individual one:
Political: I’m not sure the Countries that were part of the EU prior to opening up in 2004 would ever be getting close to war. Remember only nearly half of the Countries only joined 15 years ago, which in my opinion is when most of the problems (Or disdain) started.
Financial: I think this is just something that would have happen regardless of the EU. There are plenty of free trade deals and I’m sure European countries would have agreed these deals regardless of the bloc. In fact I’d say the deals would have had better compromises at individual country level than they would in a bloc. It may be protectionism, but I’m not sure that is always a bad thing.
Economic: Again, for me this is only good for Countries that are net benefactors from EU money. I’m also not sure huge subsidies for certain sectors is a good thing as you may as well just put it into the public sector.
Social/Education: I don’t disagree.
Other indirect benefits: I’m not sure this is necessarily due to the EU been formed as it happens with people from Non EU countries and also happened in the EU before 1992.
