Yes people will adapt by passing the cost of admin on to customers. £7bn/year spent on form filling rather than maintaining yours and my standard or living.
Of course the share of other markets has been going up, that’s why they’re emerging markets and it’s been going up by definition while we’re in the EU. We will get much better terms as part of a large trading block than as a medium sized country.
We aren’t suddenly going to start buying fresh food or time sensitive parts of the supply chain from Australia or India. We’re still going to do most of our trade with the EU. Because. They’re. Our. Closest. Neighbours.
I understand the Brexiter arguments, that’s why I know they’re nonsense. They always talk very narrowly in terms of percentages and growth rather than absolutes to hide this nonsense. The fact of the matter is we’re all already poorer and will continue to get so even if we strike all these amazing trade deals (none of which so far have gone significantly above what we already had).
It’s the same blank slate theory as radical communism. Just blow it all up then think of the possibilities. It’s the delusion of someone detached from reality and incapable of understanding the complexity of the world.
But, we’re not just a medium sized country. Britain is the 5th/6th largest economy in the world. Other countries are going to want access to our economy too - it’s a non starter. There are companies that will invest in Britain. For example, Aldi have pledged to invest £3.5bn into the UK to boost its domestic supply chains - probably because we’re leaving the internal market.
On that note, supply chains can shift, and we live in a globalised world where our supermarkets are stocked with produce from all over the world already. Again, a zero-tariff and zero-quota access to the EU market means that aside from the additional customs requirements - not a lot will change on this front.
The debate whether or not we’re better off in the EU is a waste of time because we’ve left now. I’m a Remainer, but the uncertainty around Brexit needs to be resolved and the debate around Leave and Remain need to be ended. If Brexit goes badly, which it could, then perhaps there’s a demand to rejoin the EU.
None of us here are experts, and even then, ‘experts’ get economics wrong all the time. Brexit will change a lot of things and unforeseen impacts for better or worse.
I want Brexit to go well because I want my country to do well. Let’s see how this all plays out.
