I'm not. Trading zone - yes, absolutely. But full political and economic union -no.
Reasons:- 1. The region is too diverse both economically and culturally, so there would be winners (richer countries) and perpetual losers (southern europe) 2. The system is too open to abuse i.e. little or no public accountability so democracy is at risk
The EU has many similarities with the former Yugoslavia after Tito's death, i.e. relying on mutual trust and backroom lobbying between the republics to get any decision done. But when the economy crumbled Serbia started taking money from the Yugoslav central bank in Belgrade to pay for Serbian salaries and there was nothing other republics could do about it. If you want a European state you need an authority for the case where someone misbehaves that Yugoslavia didn't have, which means an EU police and army.
I have not thought this through to the nth degree but, in principle and having lived there, I regard the model of the USA as being about right. There are States and local governments but everyone regards themselves as American. You can travel anywhere and be governed by the same federal laws, no borders, there's a huge internal market without inter-state restrictions. It is one country. The USA has many problems but I see these as being in spite of their unity, not because of it. I do accept that a USE is probably a bridge too far and would need a federal government and security apparatus but I don't see that as a negative thing. Without it, we will remain a group of disparate fiefdoms constantly squabbling over everything. It is possibly true that the USA fears a fully cohesive USE, with good reason, and actively works to prevent it coming about, reason enough to do it in my book.
Ok... but think about how USA was formed. It took a civil war.
It was a series of independent, loosely connected states, when Abraham Lincoln (and the northern states generally) decided that they wanted more power centred on Washington. The southern states disagreed: they wanted to remain a confederation of states, but no more. The unionist states continued to push for more centralist power, so the southern states opted to seceed from the union. At that point a full-scale civil war broke out. When the South lost, it was well and truly subjugated and its never been able to recover economically, because interest rate policy and political decision making favoured the north. There are a lot of parallels between the USA and the euro debacle, except, thank God, the Southern European states haven't gone to war with the Northern European states and been subjugated by superior physical force. However, if you look at what's happened in Greece lately, you might ask if the Greeks have not been subjugated by other means?
