The number of billionaires has surpassed 3,000 for the first time, and the level of billionaire wealth is now higher than at any time in history. Meanwhile, one in four people globally face hunger.

It is one thing for a billionaire to buy an enormous yacht or many luxury homes around the world. This excessive consumption can be rightly criticized in a deeply unequal world where the majority of people have very little and our planet is suffocating from relentless carbon emissions and waste. But many would reject this criticism, describing it as the politics on envy.

Yet far fewer people would disagree that when a billionaire uses their wealth to buy a politician, to influence a government, to own a newspaper or a social media platform, or to out-lawyer any opposition to ensure they are above the law, that these actions undermine progress and fairness. Such power gives billionaires control over all our futures, undermining political freedom and the rights of the rest of us.
