Common trade rules, wages, and railway gauge in a world federation

The world-federation scenario envisages common trade rules and regulations that encourage economic integration. Wage standardization is suggested as a gradual process, including a Commonwealth minimum wage that individual dominions could raise. A standardized railway gauge is another imagined consequence of coordinating infrastructure worldwide. The discussion also expects investment in science, engineering, and space exploration. Those projects are linked to a proposed government's desire to demonstrate its power and maintain public acceptance. These are speculative consequences of the scenario, rather than features of an actual imperial program.
