Of course the root cause of this is the Euro.
It did not take a degree in advanced economics to realise that linking the economies of such diverse countries as, say, Germany and Greece would only end in tears. I’m afraid, Bobbisox that prices already have rocketed in Portugal. Prices in all of the “PIGS” nations took a turn for the worse not long after they joined the Euro. Costs of touristy goods and services in those countries are about three to four times what they were ten years ago. Add into this the ridiculous exchange rate for the Euro and it’s easy to see why those countries are struggling.
The Euro needs to either undergo a radical transformation (with the lesser economies reverting to their own currencies) or fold up entirely. Economic union without political union is a recipe for disaster and it looks as if that disaster is already occurring.
I’m afraid, Old_Geezer, your idea of “petitioning to leave” is a non-starter. None of the major parties (the only ones likely to form a government) have any intention of allowing the UK electorate to even have a vote on the issue, let alone act on their wishes. The EU is so ingrained in their DNA that it would be like asking them to remove their brains.
