Both of these stories are anchored in the realities of capitalism. It is not an illusion that capitalism has transformed the material conditions of life in the world and enormously increased human productivity; many people have benefited from this. But equally, it is not an illusion that capitalism generates great harms and perpetuates eliminable forms of human suffering. Where the real disagreement lies—a disagreement that is fundamental—is over whether it is possible to have the productivity, innovation and dynamism that we see in capitalism without the harms. Margaret Thatcher famously announced in the early 1980s, “There is no alternative”; two decades later, the World Social Forum declared, “Another world is possible.” That is the fundamental debate.
