The Hegemony since day 1 of its formation in 2041 has enforced a single global language for: education, legal documents, announcements, and for communication between citizens across the various states and even planets.
In my mind (might be a bit ethnocentric) English, albeit reformed/fixed to standardize some of its quirks (which changes exactly I'm not sure of just yet) could serve as a global language. Of course I'm always open to another solution like Esperanto.
Would English be a good choice for a global language or do better alternatives exist already? By alternative it should be easier to learn and teach as well as have the capacity to be picked up by virtually anyone with minimal difficulty.
Notes:
English would be the language of the state and bureaucracy. However the Hegemony still supports local cultures and languages within the larger global culture established by the Hegemony.
English wouldn't have to be anyone's first language they would just be required to be fluent in it.
