What do we have to export:
Well, good question. We are in trouble here, but that is the case regardless of our position in the EU. We have services and high end goods, but not nearly enough. We need to address this urgently.
However, it seems to me that the remainers case is for us to be a bridgehead into the EU. A lot of this merely involves laundering dirty money and providing financial services to dodgy oligarchs (and their like). In addition we can pay minimum wage to low skilled people to make cars or steel somewhere far away from the action.
This status quo appeals to a lot posting on here (cui bono). However, is it in the best interest of our future? I cannot provide a long term blueprint for our future outside the EU, which will lead to accusations of ignorance. But nor can anyone; futurology is not science. However, we do have negotiating power, as, for instance, Germany recognises. Equally we could develop a proper education system fit for purpose, a meaningful regional policy (not a fig leaf few 10s of millions) and an immigration policy to attract the best.
According to Trading Economics, the Eurozone growth rate is expected to trend at 1% to 2020. Why? The remainers have produced a lot of facts and figures for what the Eirozone is doing well, but surely this should translate into economic growth. If not, why not?
