Re: If our chips are that good...
I'm not sure what you're trying to say here. If the UK is "25% poorer" due to the decline in Sterling, then it's 25% cheaper for the global market to invest in Britain - which do you want it to be?
As it is, FDI in the UK appears to be broadly the same, though we've had massive volatility over the last decade for some very obvious reasons that are global, not domestic in origin. It's also worth reiterating that contrary to popular opinion, manufacturing has not gone away in the UK, but in common with most Western countries, services have massively grown over the last few decades.
Of course poor countries are developing - that's where the cheap labour is. It's what gave China decades of growth (that's now slowing as their labour costs and quality of life increases), and what is driving industries to India and South America. The West will not see growth like that in our lifetimes - which is why investors keep pumping money into meme stocks and technology bubbles. Expecting otherwise is ridiculous.
Nor should it be surprising that the UK is struggling, when most of our political classes have a poor grasp of economics and just want to argue over minor readjustments in the budget. If you want to see serious growth, you need to encourage an environment where many options can be tried without investors and companies having to risk their existence each time. That 'support for risk' is what has allowed America to dominate the tech industry. Conversely, the tendency for political groups in Europe and the UK to want to tightly control the direction of investment and innovation is one strong reason for our relatively poor performance. It turns out politicians are both slow and ineffective when it comes to picking up tech trends.
Unfortunately, as usual the discussion is framed in terms of how many handouts can be directed to the right people rather than how the wider economic environment can support increased activity. In that sense, Brexit Britain is a myth - in or out of the EU, our environment for innovation has not changed due to the usual institutional feet of clay. Arguing over tax breaks and handouts is missing the point that we need more change, not less.
