Re: A good thing too
Here is my reason.
The general feeling in the EU is that they should be heading for a Federated State, with more and more power being moved to Brussles. There is legislation in their pipeline that moves things like tax harmonization closer.
This is happening at the same time as efforts to change the structure of the EU to better reflect the fact that it (currently) has 28 members rather than the founding 6 members failed, leaving the voting structures in the EU almost completely incapable of allowing any significant or controversial policies to be implemented in a reasonable time scale. I predict we will see the effect of this as they debate any UK exit deal, as I think it's going to be a long and difficult process to get them to agree to anything at all.
Without reform, the EU is fast becoming moribund, and I did not want the UK shackled to an organization that we did not join (we joined the EEC, an organization with a different purpose), that I see as having a reducing importance in the world (and, yes, I do know that the UK was instrumental in the Maastricht Treaty, although I think UK politicians at the time thought that it was a first step in reform, rather than an end in itself).
Stresses within the EU over the north/south financial policies, the increasing desire to make the Euro the currency across the whole of Europe, and the increasing pressure on the southern most countries to cope with migration pressures without assistance from the countries further away, will, in my view, tear the current EU apart.
It will only take one of the major countries to have a right-wing government elected, and IMHO we will see border control between EU countries again, and a rising reluctance to offer financial support to the poorer countries. It amazed me that the Greece situation was constrained, and this was only by other EU countries, in particular Germany, offering money to prop Greece up while it dismantled it's pension and social services to contain costs. Will the German population agree to do this again in the future? Only time will tell.
If the EU had agreed to much needed reform, I would have voted differently. But my only regret in voting the way I did is that those around me thought I did it because of immigration, which, if it was at all, was only a very, very minor part of my decision.
