OK, I'm going to have a serious crack at this one. Just for the record, I'm a full-on Remainer. I've been on protest marches, featured in protest videos, joined the LibDems, etc. But. I'm also an entrepreneur - the type who saw opportunities in the 2008 financial crash and built up a successful company. Which I'm now selling, partly because of Brexit. There'll be plenty of change coming with Brexit, that's for sure, and I want to think outside the box here.
So - what possibilities could lie yonder? Well, firstly, I can't see any possibilities if we get 'No deal'. Honestly, I just think we'll be fucked - any gains would be swamped by problems.
But assuming we get a deal, we then look outwards towards the East primarily, and the ANZAC countries (Australia, NZ, America, Canada), who will hopefully view us as 'EU Lite', i.e. access to the European time-zone and markets, but without heavy regulation. What do I mean by that? Slow-moving, really. Anything requiring consensus between 26 countries is going to move more slowly than just 1 country.
Just listened to an excellent series on Radio 4 about how the world views us - countries like Nigeria, Canada, Singapore etc., as well as Poland, and recurrent themes are admiration for our legal system (Magna Carta, Parliament), our consistency and stable history (represented for many by the monarchy), and our cultural and scientific influence (BBC, Monty Python, Oxbridge University etc.).
So our selling points are:
Time Zone and Language (straddling Asia and America, English being Lingua Franca for global business)
London (love or hate it, it's the biggest city in Europe, and the global home of finance - that brings certain unique competitive advantages)
Our widely admired legal system (Magna Carta, founder member of ECHR, Parliamentary system as a model for governance etc., also maritime governance)
Easy access / Co-operation with Europe (VERY important we get a deal)
Our education system is well respected (research universities etc., well educated workforce)
Will that be enough to attract inward investment? I hope so. And where do we want that investment to come from? China obviously, but also South Korea, Malaysia, African and South American nations. And they are what fund managers call 'high growth economies' (i.e. risky). Things are about to change radically - 'better' is a moot point. So yes, the strategy COULD pay off, and a re-distribution of resources could take the pressure off London and the SE.
But what a reckless gamble to take. I hope the Conservative Party get shredded for the next 30 years for this, I really do.
