This is also one of the things wrong with the global economy. Safety margin is necessary but inefficient, and insufficiently incentivized. In an older conversation here, someone phrased it along the lines of "a system that's highly optimized for one environment is correspondingly unoptimized for any other environment", including environments resulting from natural changes. I tend to think of it as an engine with all the tolerances honed down for efficiency, like a racing motorcycle, but with no room for grit or losing traction.
