Walter E. Williams provides us with some insight into Nonsense Ideas:

How many times have we heard: If it will save just one life, it’s worth it? The “it” could be bike helmet laws, childproof medicine bottles, or formaldehyde and asbestos safety regulations. A good economist cringes hearing such statements because they only consider the benefits of an action while ignoring the cost. Looking at benefits only, just about anything is worth doing because there’s usually a benefit. Let’s look at it.

According to the National Highway Traffic Safety Administration, some 43,443 people were killed on the nation’s highways in 2005. If Congress were to enact a 10 miles per hour national speed limit, we’d save thousands of lives each year. You say, “Williams, that would be stupid and impractical!” My response to you is: But look at all the lives that would be saved. What you really mean by stupid and impractical is that preventing thousands of highway fatalities is not worth the cost and inconvenience that would result from having to poke along at 10 miles per hour. Of course, calling a 10 miles per hour law stupid and impractical is a more socially acceptable way of saying those saved lives aren’t worth it.
