Cities in the US or Canada that offer comparable accommodation, eating and shopping opportunities are pretty miserable places to live in. Central London is beautiful, green and wonderful to walk around. It takes a very specific kind of person to enjoy walking around Manhattan on a regular basis.
London is also conveniently located wrt. top holiday destinations like the Alps and south of France.
London offers so much more to the oligarchy than just banks and lawyers.
Fuck, what other cities reliably offer Uber Lux? And I don’t mean the watered down American version with Suburbans and the likes.
The oligarchs will still remain in London even if draconian KYC laws might force them to rent instead of own, there aren’t any realistic alternatives.
Of course the “normies” will never understand this, they can’t even imagine the lifestyle. They have no idea what other great cities lack, because they’d never even dream of needing such services.
