>Just think of how much smaller cars could be if we removed seatbelts and airbags! A stairway is going to take up a lot more space in a building than seatbelts and airbags are. By my estimation my apartment building would lose over 10% of its living space by doubling its amount of staircases. However, I doubt that it would make a big difference in the cost of housing itself. It seems to me that housing is pricey because it's an investment rather than the labor cost being prohibitive.
