Adam Smith: businessmen were, on the whole, more trustworthy than diplomats.

Is this saying more about diplomats than businessmen?
The "Wealth of Nation" author believed "repeat business was usually more important to businessmen than to diplomats. Smith argued that diplomats frequently broke treaties since treaties are made infrequently. As a result, the gain from breaking treaties often exceeds the gain from living up to the obligations imposed by the treaties. Another, much more famous, result of Adam Smith shows that under certain conditions, businessmen in competitive industries would promote the general welfare, even though they were only trying to increase their profits."
