1. The single currency
The Euro is the Exchange Rate Mechnism you cannot get out of.
A single currency needs a single country to love it and pay for it.
Joining a single currency is like taking out a bank account with the neighbours. You inevitably fall out over the overdraft.
A single currency starts as an act of friendship with the neighbours, and ends in acrimony like a bad marriage.
2. “Seeking to change our relationship with the EU, or pulling out of the EU would destroy 3 million export jobs” (Usual federalist line)
If the UK renegotiates or the people vote to pull out, Germany will still want to sell us her BMWs and France her wine
The EU would not try to damage our trade with them, as they sell more to us than we sell to them
China has millions employed in making export goods for the EU. Why havn’t those jobs been lost, as China is not a member of the EU?
3. “If the UK renegotiated or the people voted to pull out, she would no longer have any influence over the laws and regulations made in Brussels” (usual federalist line)
The UK has no special influence over the laws made in the USA, India or China, but still trades with them quite happily.
The USA and China have no influence over EU laws, but they sell a lot of goods into the EU
How much influence has the UK had over EU employment laws, social policy, the Common Fishery Policy, the Common Agricultural Policy and all the rest, where the UK has been seeking change but not getting it for years?
4. The single or common market
How many laws do you need for a single market?
Why do you need more than the simple rule that if a product is of merchanidsable quality in the home country , it can be offered for sale in the other countries of the area? (The Cassis de Dijon judgement)
The UK does a large majority of its service sector trade with countries outside the EU. Service trade requires a deeper relationship than trade in goods and is helped by a common language. Federalists just quote trade in goods figures.
