Which really drives home the point that we as a society have decided to accept a certain level of risk. That, at a certain point, we don't allow safety concerns to get in the way of getting shit done.
I mean, we could make stairs safer. We could install foam pits at every landing, cover the steps with tons of padding like at a climbing gym, then make everyone ascending or descending put on a harness and clip onto a guide wire. We have the technology to do all of those things, and it probably reduce the number of people who fall down the stairs and crack their skull on the concrete, but we don't. We don't because we accept that a few people dying on occasion is a better outcome than spending the time and money to completely sterilize our world.
It's more complex than that. Installing safety systems requires additional work, which adds additional risk of injury. Being risk free is not only prohibitively expensive, it's impossible.
And that's not even getting into the fact that people take fewer precautions when things seem safer...
