UK does not benefit. However how many of us think of the UK when looking at how to sell, where to sell, what to sell? I know its not a factor in my calculations. In terms of customers - they can get the products without paying extra, without customs delays and returns are relatively simple. In terms of the business - the jobs will be where the work is. If needs a distribution centre themselves then that is what is done. Local jobs in the local area for EU sales rather than UK jobs. Though jobs are a cost of business - we should not be looking to create or keep jobs simply for the benefit to the country, only benefit of the company or long term plans. May be a side effect that jobs are created or kept by business decisions. But unless someone else is paying for them (a la furlough scheme) then no reason a job is paid for simply to benefit the country. UK business selling to French customers from a French warehouse..... the profits end up where? UK business? And who gets to tax the UK company? The French? Or the British? What would not benefit the country at all (bearing in mind what I said about it not being a factor in decision making) - is to simply move the business entirely to the EU. If that is where the customers are then it makes sense.
