Personal incentive is the most underrated aspect of American life. It’s because of self interest that capitalism thrives: Two parties transacting, each willing to give up something of value in order to obtain something else of value that better serves their interests.

It is also the reason many of our politicians and public figures behave the way they do. Asking ourselves what incentive a person might have for making a particular decision guards against deception and aids in uncovering the truth.

When someone is earning tens of millions a year spreading fear of an impending global disaster, it does not automatically mean that the issue is false. It does mean, however, that this person has a motive in seeing the fear continue.

When someone attains fame by convincing millions they are victims of racism, it does not mean that racism doesn’t exist. It does indicate, though, that this person has incentive to see the problem persist.

When a politician places personal achievement above the health of the nation, it does not mean that he or she does not truly care about the issues. It is a signal, though, that such a person has a vested interest in the defeat of a like-minded candidate.

To the contrary of these examples, when someone has to be persuaded to run for office, or when a candidate takes a pay cut to seek elective office, or when a person shies away from the media limelight, it does not make such a figure correct on the issues. It is an indication, however, that he or she has the best interests of the country at heart.

Motivation matters. Don’t ever forget that.
