For the whole world? As a single economic and political entity? That would be an odd and strenuous task.
My view is that it can only be done country-by-country. The data for a global picture just doesn’t exist as far as I know.
Paul Mason missing a number of important points.
It’s easy enough to make ‘the numbers add up’. You simply levy a tax equivalent to the amount you want to spend. Less easy is raising that tax in a way that works (and by that I mean that it brings in the required revenue without doing damage to the wider economy).
Thomas, thank you for this response.
I should have been more explicit in the article, that the UBI outlined only replaces transfer payments (welfare/benefits). It would not replace social care or health care provision or any other forms of social protection and support.
