Please help me recollect the author and the title of the following scifi story.
In 1990s I've read a short story (or novel) in which some ruler (or government) sprayed some narcotic gas in big building (or over the city) to prevent people to see the reality as it is. So people are happy and think that they live in a wonderful city/building. Main character at some point starts to see the ugly reality (or less likely that he could see it from the beginning of the book) - people are actually poor, sick and starving, etc.
Initially I thought it could be Jan Weiss's novel House of a Thousand Floors, but it doesn't seem like it.
