What the UK and other countries do is the opposite extreme.

You've lived all your life in the UK.

You became a billionaire.

Now you move to Dubai.

And that's it.

Immediately on January 1 of next year, you have nothing to pay anymore to the UK.

Both of these systems are too extreme.

And so what I propose is a kind of middle ground.

where taxes would follow you for 5, 10, 15 years.

And the logic is obvious, right?

If you've become a billionaire in the UK, that's in large part because you've benefited from public infrastructure and education and health care and all the public spending that has allowed your businesses to thrive.

And so there is no natural right, once you've become extremely wealthy,

to secede from society and to say, that's it.

I have no tax to pay anymore anywhere in the world.

If you move to a country that taxes you as much as the UK, then that's fine.

The UK would not collect anything extra.

But if you move to a low tax country, then the UK should collect the difference so that it would become neutral

to live in London or to live in Dubai or to live in Switzerland, same tax bill in all cases.

Yes.

The reality is that it's our failure to effectively tax the super rich today, which is at the center of the public finance problems that we have in the UK, but also in France, in many countries.
