Euro and the economy: The final countdown?

The economic crisis in Europe has become the new normal and every attempt to fix it has failed. So why does the Euro, let alone the EU, continue to exist? Is there a distinction to be made between fiscally prudent countries and their irresponsible and profligate neighbours? And why is there such hostility to the idea that countries like Greece, Spain, Portugal or Ireland might be better off with devalued currencies to increase their competitiveness? Closer economic integration seems the only game in town, but surely there is a basic democratic right to decide how our wealth should be distributed? Speakers in this Battle of Ideas debate do battle over the causes of the problem as well as the answers. Who is right?
