Did you ever read Red Dwarf – Better then Life (I think) when Earth is a dumping planet for all interstellar rubbish? Lister is the leader of the giant cockroach inhabitants.
Or Good Omens, where one of the four horsemen (Famine) is a business man heading up companies like McDonalds and responsible for eating disorders and keeping people obese on food with less nutritional value then cardboard?
Maybe Doug Naylor & Rob Grant (Grant Naylor) and Terry Pratchett & Neil Gaiman were onto something!
Just a passing thought!
