Increasingly, people around the country and the world are realizing that the series of intersecting crises we face are not by chance, but by design. From staggering wealth inequality, to the looming threat of climate change and irreversible damage to our ecosystem, to surging xenophobia, racism, and authoritarianism, these crises are generated by an economy structured to concentrate ownership and power. And yet, many of the solutions being put forward focus on merely regulating or reforming the existing institutions that make up this extractive economy. The time has passed for simply tinkering at the edges of this system. Instead, we need to develop the architecture of a more democratic and just economy, and we need to do it fast.
