Is it possible that some of the areas outside of London may benefit by having more competitive trade pacts with individual nations outside of the EU? One note on productivity in UK: My observation of UK business culture can be summed up as low-energy and stagnant, and that's compared to US business culture, which I don't like. An example of this is how low developer salaries are in the UK compared to other nations, relative to managers and bosses. I was blown away by how overpaid the managers are in the UK, and how underpaid the "doers" are. My company's UK office reflects this. They are a notably low-energy group compared to our other offices. There are bright lights who seem to be cowed into submission by a cultural norm of never showing excitement or passion in the workplace. I'm sure there are benefits to removing emotion from interactions to an extent, but wow does that feel suffocating.
