You’re right we have an unsustainable trade deficit with the EU among others.In the case of the EU we also pay a fortune in net contributions and have to agree to allowing unelected commissioners and people like Merkel and Juncker and Tusk and foreign majority vote to rule over us,for the privilege.
Staying with the EU fixes any or all of that that how ?. Oh wait you think it’s better to go on paying them and to keep importing their stuff until we can no longer afford to pay for the resulting debt and would rather be ruled by foreign interests who you have no democratic control over.Rather than re building our own industrial base and telling the Germans to do one.
