Of course it's an experiment in that we have no idea at all how it's going to pan out. You no doubt disagree, but I think that Brexit has helped Trump in his campaign, and it will no doubt help Le Pen in the upcoming French elections. For that reason I do hope it fails miserably, as a world with a mentality represented by people like that and Nigel Farage is a considerably worse place.
We have to put things in context. For most of our membership of the EU, we have been one of the foremost champions for free trade, and indeed were one of the core cheerleaders for TTIP. The thing is, whilst we can debate the intentions of leave voters, the one thing that binds populists around the world is a desire to put up the barriers to the outside world, whether socially via immigration controls or economically via protectionism.
So this previous notion of Britain as a cheerleader for globalisation has been torn up and tossed away as far as I can see, and I certainly don't expect them to take what we had with the single market and replace it with a version on steroids. After all, 'trading with the world' offers the risk of jobs being lost just as much as through migration, and there appears a distinct mandate to stop that.
And that's a terrible thing imo, especially as the government already has at its disposal things that can help people who suffer from change in the labour market. The thing is, they don't invest in adult education whatsoever. Their dedicated fund to help those disrupted by globalisation is an insult to the very concept.
Likewise, their approach to dealing with movement in the labour market is equally dire. There is no flexibility to what is a largely incredibly centralised system of governance. I've said before, but if (for example) Nissan decided to move to Liverpool and therefore all of it's workers and supply chain needed to move cities, Liverpool would be no more equipped to deal with that internal migration than if 50,000 new people moved to Liverpool from Poland. Migration, whether internally or internationally, is widely believed to be a key element in a fruitful population, and certainly in tackling poverty, yet we have a society that does little to support that, and leaving the EU will do nothing at all to change things.
