When a world empire becomes a federal Commonwealth

A British empire that absorbed the world would acquire a global tax base and face the problem of governing it. The imagined solution is a federal arrangement, with London as the financial and governmental centre and dominions handling domestic affairs. Ambitious politicians could seek office at the global level, creating an incentive to remain within the federation. Russia, China, and the United States would probably be divided into several dominions to balance their influence. The discussion calls the resulting system a British Commonwealth of Earth and makes its survival dependent on how it governs people. The scenario then considers common economic rules and large scientific projects as possible consequences of that federal organization.
