The coronavirus pandemic has the potential to lead to an increase in inequality in almost every country at once, the first time this has happened since records began. The virus has exposed, fed off and increased existing inequalities of wealth, gender and race. Over two million people have died, and hundreds of millions of people are being forced into poverty while many of the richest – individuals and corporations – are thriving. Billionaire fortunes returned to their pre-pandemic highs in just nine months, while recovery for the world’s poorest people could take over a decade. The crisis has exposed our collective frailty and the inability of our deeply unequal economy to work for all. Yet it has also shown us the vital importance of government action to protect our health and livelihoods. Transformative policies that seemed unthinkable before the crisis have suddenly been shown to be possible. There can be no return to where we were before. Instead, citizens and governments must act on the urgency to create a more equal and sustainable world.
