Yeah, that's the central question.

And so probably the most important thing to understand in all of that, the most important thing to understand is that

this tax exile, out migration by the very wealthy, it's not a law of nature.

It's not like gravity.

It is something that we can fight with appropriate policies.

So how should we do it?

I think the UK should say, look,

If you've lived for a long time in the UK and you became really rich in the UK and now you move to another country, then the UK is going to keep taxing you.

It's not exactly an exit tax.

It's more like a trailing tax.

It means that you're going to be considered as still a resident of the UK forever.

for tax purposes for a number of years, like five years, 10 years, 15 years, we can discuss.

And look, there's one country that does that in some sense, which is the US.

The US says, if you have US citizenship and you move abroad, you have to keep paying taxes in the US until you die.

Maybe that's too much.

No, look, you were born in the US.

Your parents moved when you were two months old.

You never set foot again in the US.

And you have to pay taxes in the US until you die.

So that's one model.
