An airplane pilot flies with 300 people on board. There is a clear negative externality problem here. If he crashes the plane, the individual cost to the pilot is his own death. The social cost is the death of 300 people. Therefore, commercial pilots must undergo a rigorous training, testing, and certification process, much greater than a mere private pilot who flies solo.

Consider now nuclear deterrence. The US president is in control of the nuclear button. If he starts a war, he may lose his life. This is an individual cost to him. But the social cost is far greater: billions of people will die, and the world will be poisoned for the next 10,000 years, so that even future generations will suffer.

If the president has a death wish or feels like playing a game of chicken, he might do something very rash. If only he died as a result, no one would care. The president lived by the sword, and he died by the sword. It’s very fitting. But in so doing he’ll take the whole world into the grave with him.

The voters don’t vet presidents nearly as well as airlines vet pilots. The externality problem is enormous. We’re all hostages to the mental health of a single man. Mutually assured destruction is an untenable strategy for peace according even to an elementary economic analysis.

Integration is a bad idea, since blacks living among whites become dispirited when they realize they can’t possibly measure up to whites.

Let blacks stew in their own juices and “act black,” the way nature intended.

The endless squabble between the “liberals” and “conservatives” is merely a dispute between demons and devils.

Both factions in fact hate libertarians more than they hate each other.

By promising tax increases, the Dems are trying to divide the people and to excite in the working and middle classes the unholy desire to plunder and steal from the “rich.” Folks, stay reasonable and reject this evil plot.

Stuart Basden, in presenting his list of leftist causes, goes so far as to say:

In no way do I intend to marginalise or discredit the experience of people who have been labelled ‘insane’ by a normative system, nor who identify as being ‘insane’.

But insanity is not an identity but precisely absence of one.

An identity is a complex integrated self plus virtuous character belonging to a person who knows who is and is at peace with who he is.

Insanity, on the contrary, is spiritual and mental chaos coupled with great suffering. It is disintegration of the self, spiritual unraveling. It’s not an identity. It’s the previous identity falling apart into pieces.

In extreme cases, the very phrase “I am insane” is self-contradictory. A madman is not a one “I”; he is legion.

The left does not care about the Muslims in foreign countries whom the US government is constantly bombing; but they have declared them an oppressed class in the US where they are in no danger whatsoever.

America can “afford” so much of its implausible socialist agitation and dysfunction because it still has few genuine competitors in the world.

Other nations need to step up their game and, though laissez faire, get mighty prosperous both for their own sake and to give US politicians an incentive to do something right.

The online book, When Abortion Was a Crime, is notable for the author’s complete failure to grasp what a pregnancy actually is — the bearing of a child, instead of “the cessation of the menses” which “indicated a worrisome imbalance in the body and the need to bring the body back into balance by restoring the flow.”

Do married couples fatten each other up to make each other uglier and hence less attractive to the opposite sex to prevent extramarital affairs?
