CAMBRIDGE – The most widely held theory of politics is also the simplest: the powerful get what they want. Financial regulation is driven by the interests of banks, health policy by the interests of insurance companies, and tax policy by the interests of the rich. Those who can influence government the most – through their control of resources, information, access, or sheer threat of violence – eventually get their way.
It’s the same globally. Foreign policy is determined, it is said, first and foremost by national interests – not affinities with other nations or concern for the global community. International agreements are impossible unless they are aligned with the interests of the United States and, increasingly, other rising major powers. In authoritarian regimes, policies are the direct expression of the interests of the ruler and his cronies.
