But the bottom line for the society as a whole is fewer armored vests. Is that a good choice?
If I have 100,000 vests, 80,000 of which work, am I better off than if I have 80,000 vests, all of which work?
Is that a good choice?
Police officers are putting on armored vests without having to worry if they will actually stop a bullet or not. Is that a good choice?
