> Billionaires are a very small group. There is far more wealth held by people with assets of, say, over £100m, or even £10m?

Which is precisely why we can't 'eliminate billionaires'.

Because before long it's a push for full-on communism, and even owning £100k is too much.

And unless you can destroy capitalism on a global scale, there'll always be countries eager to take in very wealthy people.
