No, but we only see the small picture. UK is still a go-to destination for many wealthy foreigners from HK, China, SEA, ME and even ex-USSR. Yes, there are more taxes now, but for most of them the wealth is already either wrapped in corps or structured in some other way. So yes, many will leave, many will come, not much will change. There is no significant drop in 2+ mil properties in London, there is still a huge waiting list︀ to the best private schools etc.
The same with Spain - second most aggressive tax︁ enforcement in the world yet people are coming in droves, new multimillion villas are built︂ on every Costa every day, no drop in prices.
So yes, people are ok with︃ being sodomised by tax authorities as long as it comes with a lot of lube,︄ jar of sangria and a bit of sunshine.
