An acclaimed economist's observations on four years of events that have shaped the world. In this new volume of essays, renowned economist Thomas Piketty takes measure of the world since 2020: leaders grappling with the aftershocks of the global pandemic; politics shifting rightward in France and elsewhere; and wars breaking out and escalating, from Russia's invasion of Ukraine to the conflict in Israel and Gaza. These essays are Piketty's vivid first draft of history-on the rise of China, the climate crisis, income and taxation, discrimination, and beyond-as well as a blueprint for achieving equity in our rapidly changing global landscape. Despite the gathering clouds, Piketty continues to find reasons for hope.
