If we look to benefits only, we'll do darn near anything because there's always a benefit. The National Highway Traffic Safety Administration reported that there were 43,443 highway fatalities in 2005. If we had a maximum speed law of 15 mph, the death toll wouldn't be nearly as high, probably not even as high as 500. You say, "Williams, that's a crazy idea!" You're right, but let's not call it crazy; it's more accurate to say: saving some 43,000 lives aren't worth the cost and inconvenience of a 15 mph speed limit.
Suppose there was a one percent risk of a $10,000 loss, how much are you willing to pay to try to prevent or insure against it? I doubt whether any reasonable person would be willing to pay $9,000, $5,000 or even $1,000, though he might be willing to pay $100. Surely there's a benefit to preventing a loss, but at what cost?
Let's apply cost versus benefits to anti-terrorism expenditures. Wyoming has two major cities: Cheyenne, its capital, with 53,000 population; and Casper, with 50,000. Federal and state homeland security anti-terrorism expenditures in 2007 totaled $6,673,910. What is the risk of Wyoming being a terrorist target and, if so, what is the expected cost in terms of human lives and property?
There's no precise way to determine Wyoming's risk of a terrorist attack and its cost, but simple reasoning suggests that too little or too much can be spent. The effect of spending too little might result in a devastating terrorist attack that could have been prevented. The effect of spending too much is less obvious because the victims are invisible. For example, purchase prices for new dump trucks for snow and ice removal range between $140,000 and $160,000. How many Wyoming lives could have been saved had some of the anti-terrorism expenditures been spent on additional dump trucks to clear streets and roads of snow and ice? There are many other lifesaving expenditures but the point is that a dollar spent for anti-terrorism is a dollar that can't be spent elsewhere where it might possibly save more lives.
The 1984 National Organ Transplant Act, which prohibits payments to organ donors or their families, creates benefits in the form of feel-good ethical values at a huge cost of lives. That's because organs must be supplied to recipients at zero price. Huge shortages are the result, as it would be if cars, homes, food, dental services and clothing had to be supplied at zero price. That's precisely the finding by Professors Randolph Beard, John Jackson and David Kaserman in their article "The Failure of U.S. Organ Procurement Policy," published in the Winter 2008 edition of the Washington, D.C.-based Cato Institute Regulation magazine.
