You speak in the past tense but this hasn’t actually happened and shows no signs of happening in terms of banks relocating jobs and capital. If anything London is getting stronger.

Let’s hope that the NHS gets properly funded and doesn’t get privatised. Because the US vaccination rollout is a shambles.

Japan: You guys have vaccines?

In all honesty, this statement is fairly close to being hilariously wrong. The US vaccinates more people per day than any other country in the world. The reason why the UK has a higher per-capita vaccination rate is A) there's less of you to vaccinate, and B) the UK isn't doing two doses. The former makes the rollout easier - there are countries like Israel where they're close to vaccine herd immunity as they simply needed fewer doses. The latter is a calculated risk only somewhat supported by the available medical data. I don't expect every country to adopt First Dose First, especially if they've already given two doses to high-risk populations that would benefit from getting half their protection sooner.

Trust me, there's plenty of other things you can harangue the US about all day - vaccines aren't one of them.

I trust "the math" that shows a better population outcome there, even though individuals will have higher risk profiles this way.
