I actually wrote a short story in 8th grade (long before Demolition Man came out) that touched on something similar.
This was the height of the Reagan-era Cold War, mind you, so everyone was thinking geographically. Eastern Bloc. Soviet Bloc, etc.
But I thought it might be interesting to explore a dystopic future where geography and nationality were shoved to the back, behind corporatism. At the time, the Soviet Union wasn't allowing McDonald's or Coca Cola into their borders, because those were too symbolic of the USA's power in the West. They did however allow Pepsi in. And perhaps some other group of food franchises, like KFC or something?
Regardless, I took that reality as my inspiration and I broke the world into the McCoke Bloc, and the Pepsi Bloc. They still roughly aligned to the East and the West, but since Pepsi originated in the USA, they held some power and influence within the McCoke Bloc. And the McCoke Bloc had made some trades and corporate buyouts, to obtain some influence within the Pepsi Bloc. There was a lot more to it than that, but that's the basic premise, so years later when I heard that line in Demolition Man, I couldn't help but smile and think that somehow, they stole my idea.
