So, having not left the EU, I thought we'd be doing BETTER than we are now. I remember feeling shocked hearing this:
When that referendum result came in NOTHING ACTUALLY CHANGED. All we had was speculation about a future change (Single Market, Customs Union etc...)
Right now we have a moving train whose tracks lead off a cliff. There's some panic on board. Some people have jumped off. But many people are saying, "You said we'd crash, but we're fine now, so we can't trust you"
So to use the state of the UK pre-Brexit to say we can't trust predictions, when the state of the country pre-Brexit, is based on predictions...
