Economic ignorance allows us to fall easy prey to political charlatans and demagogues, so how about a little Economics 101?

How many times have we heard “free tuition,” “free health care,” and free you-name-it? If a particular good or service is truly free, we can have as much of it as we want without the sacrifice of other goods or services.

Take a “free” library; is it really free? The answer is no. Had the library not been built, that $50 million could have purchased something else. That something else sacrificed is the cost of the library. While users of the library might pay a zero price, zero price and free are not one and the same. So when politicians talk about providing something free, ask them to identify the beneficent Santa Claus or tooth fairy.

It’s popular to condemn greed, but it’s greed that gets wonderful things done. When I say greed, I don’t mean stealing, fraud, misrepresentation or other forms of dishonesty. I mean people trying to get as much as they can for themselves.

We don’t give second thought to the many wonderful things others do for us. Detroit assembly-line workers get up at the crack of dawn to produce the car you enjoy. Farm workers toil in the blazing sun gathering grapes for our wine. Snowplow drivers brave blizzards just so we can have access to our roads.

Do you think these people make these personal sacrifices because they care about us? My bet is they don’t give a hoot. Instead, they along with their bosses do these wonderful things for us because they want more for themselves.

People in the education and political establishments pretend they’re not motivated by such “callous” motives as greed and profits. These people “care” about us, but from which areas of our lives do we derive the greatest pleasures and have the fewest complaints, and from which areas do we have the greatest headaches and complaints? We tend to have high satisfaction with goods and services like computers, cell phones, movies, clothing and supermarkets. These are areas where the motivations are greed and profits. Our greatest dissatisfaction is in areas of caring and no profit motive such as public education, postal services and politics. Give me greed and profits, and you can keep the caring.

How about the idea that if it saves just one life it’s worth it? That’s one of the stated justifications for government mandates for childproof medicine bottles, gun locks, bike helmets and all sorts of warning labels. No doubt there’s a benefit to these government mandates, but if we only look at benefits, we’ll do darn near anything because there’s always a benefit to any action.

For example, why not have a congressionally mandated 5 miles per hour highway speed limit? According to the U.S. Transportation Department, there were 43,220 highway fatalities in 2003, with an estimated cost of $230 billion.

A 5 mph speed limit would have spared our nation this loss of life and billions of dollars. You say, “Williams, that’s preposterous!” You’re right. Most people would agree a 5 mph speed limit is stupid, impractical and insane. That’s one way of putting it, but what they really mean is: Avoiding 43,220 highway deaths and the $230 billion by a 5 mph speed limit isn’t worth all the inconvenience, delays and misery.

Admittedly, the 5 mph speed limit is an extreme example, a reductio ad absurdum. Nonetheless, it illustrates the principle that our actions shouldn’t be guided by benefits only; we should also ask about costs. Again, when politicians come to us pretending they’re Santa Clauses or tooth fairies delivering benefits only, we should ask what’s the cost; who’s going to pay and why.
