You have an interesting take
Whatsoever it is, for sure it will not solve any of the root causes of UK's problems. The lack of structured internal investment with good planning and execution is what has been causing the UK to fall behind Germany.
For me, it seems that the British ate being steered away from important decision processes like "should we really invest in another war?" And "should we increase the number of doctors and care workers that has being stagnated for the past 15 years?" Or even "should UK invest more in telecom communication?"
As many other countries, UK has turned into technology hostage. Luckily, the incredible background created by geniuses of that past still holds up but the lag is already showing.
Nothing would sabe Britain if certain president charged taxes for cloud services, AI or processors and GPUs.
