- They kept their old monetary unit (GBP)
Frankly, Euro is a gooberty gook. And the ECB has no clue and no powers. While some countries in the Euro zone can benefit and recover from a weak Euro, others need a strong Euro. So how does it help? A weakened GBP will help more exports. By the way its just markets reacting irrationally. My take is, GBP will be better off than Euro.
- They kept the *right to refuse entry* (not signed SENGEN)
Good, they can refuse the entry of terrorists that Germany and friends are welcoming with open arms.
Spain is in trouble with high unemployment (21%) with youth unemployment at a staggering 45%. And the longer it stays in the EU the longer it will have to suffer. A currency devaluation can help Spain too, just like it would help Greece. But Germany will not let that happen, because they are doing extremely good while Spain suffers. But why should Germany care?
