There are many excuses for failing to tax the ultra-wealthy. The truth is that governments don’t tackle the problem because they don’t want to

There is one political problem from which all others follow. It is the major cause of Donald Trump, of Nigel Farage, of the shocking weakness of their opponents, of the polarisation tearing societies apart, of the devastation of the living world. 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.
