Today, wealth inequality between the world's richest and poorest continues to grow. According to an Oxfam report published in January, the world's wealthiest 26 individuals had the same amount of wealth as the poorest half of the population in 2018, the latest figures available. During the same period, the wealth of the world's billionaires increased by $900 billion ($2.5 billion per day), while the wealth of the poorest half of the population (3.8 billion people) fell by 11%, the Oxfam report found.

In 2019, Bernie Sanders said billionaires should not exist, and billionaires themselves, from Gates to Zuckerberg to Ray Dalio acknowledged that something must be done about the wealth gap.
