In those days, high-rise buildings had virtually no awareness of fire safety, and there was only one staircase for going up and down.
If there hadn't been any major safety incidents that sparked public outcry and led to government intervention with mandatory policies, then real estate developers and construction companies would definitely save money where they could, without spending a dime on these "insignificant issues."

Even during World War II, when the German Army attacked Stalingrad, it took a lot of effort to fight the Soviet Army for a single building.
