Who mentioned Afghanistan?
you evade my point that most billionaires, like most other people, prefer to live in a place that is stable, prosperous, has an effective rule of law, and a healthy, educated population.
taxes pay for the public spending which achieves this.
Who do you know in the UK that has caught polio from their housemaid, or been unable to find skilled and literate workers, or whose children have been kidnapped and ransomed by the local armed clan?
No, I didn't miss your point and I certainly didn't evade it. I agree with what you said, that this country has other attractions as well as the financial incentives. However, I maintain that if you tax the wealthy beyond a certain point they may decide to up sticks.
