I’ve spoken of two cycles of popular movements since World War II: the first (1945–1978), about demanding the rights of national citizenship, the second (1978–2008), over access to capitalism itself. It seems significant here that in the Middle East, in the first round, those popular movements that most directly challenged the global status quo tended to be inspired by Marxism; in the second, largely, some variation on radical Islam. Considering that Islam has always placed debt at the center of its social doctrines, it’s easy to understand the appeal.
