Mills attributes the decline of anti-imperialism to the new phase of informal white supremacy that formed in the mid-20th century. Because both philosophy and politics are stuck using “abstract and general categories,” they portray the world as equal, while forgetting to address the cumulative inequalities created by 500 years of
formal white supremacy. Now, identifying white supremacy as a global political system is much harder than in the past, when European colonialism made it obvious. However, Mills’s theory of the racial contract is an attempt to make this system visible again.
