The elites — corporate owners and managers, government officials, and military commanders — are people who have been selected for certain qualities: loyalty to the system, competitiveness, and hunger for power. Often they are literally bred for their roles. Like George W. Bush, they are people born to wealth and power, and raised to assume that privilege is their birthright. These are people who identify with the system and the status quo; they are constitutionally incapable of questioning its fundamental assumptions.
Moreover, the elites are guided day-to-day by a set of incentives that are built into the system itself. Managers who pursue immediate gain get ahead, while those who make short-term sacrifices in order to preserve long-term stability are often at a disadvantage. Likewise, managers are rewarded who keep up appearances, who generate good news, and who exude confidence. Confessing errors accrues no benefit; instead, managers are encouraged to deny shortcomings and to blame competitors or subordinates.
Such conduct is hardly unique to elites; everyone behaves in this fashion from time to time. But the system, in grooming its most prominent caretakers, selects for these behaviors; it carefully fosters some personality types and excludes others: assertive individuals who think concretely come to the fore, while creative dreamers fall by the wayside.
Leaders are often good liars: they are people who have learned how to tell others what they want to hear. We voters tend to elect and follow such people. Even if we know at some level that we are being lied to, we are flattered and pleasantly illusioned (we hate being dis-illusioned). The best liars are able to convince themselves of the truth of what they are saying, so that, in their own minds, they are not lying at all; as a result they can be eminently convincing. J. P. Morgan (who knew something about power and influence) once said that “A man generally has two reasons for doing a thing: one that sounds good, and a real one.” Some of us are very good at deluding ourselves that the reason that sounds good is the real one.
