> It is a little bit of both influencing each other, but the system in London is definitely the killer app

I’m super unconvinced this is true. I know many “oligarchs” living in London, most of them do not keep their money in the UK.

I think the people writing about London from a tax haven/money laundering perspective tend to have rather little insight into the quality of life aspect. It’s easy for them to mistakenly assume that the system is the main draw, but the reality on the ground seems rather different.

For very rich people that want to live in a city, London is absolutely the #1 destination.
