Remind me "The Three Stigmata of Palmer Eldritch" from Philip K. Dick. Selected (clever) people are sent as settlers on Mars, but everybody know it's crappy as hell and that people are surviving thanks to drugs which allow them to remind theirselves what Earth's like. People try to get crazy on Earth to fail tests and avoid being sent there.
