BlueBelle, it is the EEA Country's that are not doing well. The EU being a trading organisation pretending to be a democratically elected Government is failing. If we remain tied into "ever closer union", rather than just free trade, within just a few years we shall be dragged into a financial and trading disaster. Germany and France financial prediction by the IMF for the next two years at least is very poor. Italy is on the brink of bankruptcy as of course Greece is already and being sustained only by massive loans which it can never repay, but the EU sustains it rather than admit Greece is unable to comply with EU rules and regulations.
There is high unemployment, social exclusion in the big cities of EEA Country's due to free movement of people from poorer Countries, placing pressure on unplanned housing, health care, education and infrastructures, creating enormous discontent, and divisions. Denmark known for it's liberal attitudes is suffering from legal migrant fatique and is reacting to this. All in all, the UK is doing well. The reason for leaving the EU is simply that as a trading organisation they imposes social regulations and directives using the single trading market to control member States.
The rigid doctrine, tight unbending controls, regulations and directives, protectionist policies, and now the founding of an EU Military under the guise of "peace keeping" encroaching now upon NATO. These are the very things that the EU was formed to prevent, Militarisation of Europe and extreme far Left and far Right politics, ironically created by the EU.
So if your looking for reasons to leave the EU, look to the EU, analyse, investigate, ask question, look behind the facade to see what exactly the EU is. There you will find the reasons why the UK is leaving.
We are not leaving Europe, we are leaving the EU. Why one would think that friendships will be affected baffles me. We are leaving a trading organisation not a Nation State. There are no citizens, other than the artificial ones created by the EU, when they decided that 28 Nations would no longer be citizens of their own Country but would be EU Citizens, how could we fall for that!
