This is an economics question.
Say 1 in 1000 security guards die in a year. Of the ones who actually show up it’s like 1 in 100.
The federal government estimates the value of a statistical life at 10 million. So guards lose 100k each year in death risk.
The salary of a security guard is 14 dollars per hour so it seems economically irrational.
Are security guards actually not economically rational?
And by the way you can interpret this as an art gallery problem but with death risk.
