It is simply stated: the extreme wealth of a small number of people.

It can also be quantified. The World Inequality Report (WIR) 2026 shows that about 56,000 people – 0.001% of the global population – corral three times more wealth than the poorest half of humanity. They afflict almost every country. In the UK, for example, 50 families hold more wealth than 50% of the population combined.

You can watch their fortunes grow. In 2024, Oxfam’s figures show, the wealth of the world’s 2,769 billionaires grew by $2tn, or $2,000bn. The total global spending on international aid last year was projected to be, at most, $186bn, less than a tenth of the increment in their wealth. Governments tell us they “can’t afford” more. In the UK, billionaires, on average, have become more than 1,000% richer since 1990. Most of their wealth derives from property, inheritance and finance. They have become so rich, in other words, at our expense.

The issue affects every aspect of policy. Trump is not seizing Venezuela’s oil wealth for the sake of the US poor. He couldn’t give a damn about them, as his “big, beautiful bill” – robbing the........
