A recent holiday-themed 'charity' post over on Freakonomics prompted me to express the following thoughts. This is a deeply felt, and I believe deeply true, conviction that I've held for quite some time, but have never expressed quite so clearly, largely for fear of being perceived as a bad, bad, contemptible person.

All too often, fear of how we will be perceived prevents us from speaking what we know is the truth, when that truth is of a cynical nature; and this allows the spreading of naive, nice and rosy false beliefs. But we should not have a bias in favor of naive, nice and rosy beliefs. We should not speak the truth only when it is nice. We should speak it always, or else people will act on false premises, and do damage because they believe in nice falsehoods instead of doing good on the basis of sound, real truth.

So here it is. The truth about giving.

To give without reservation is to spoil. To give is to bleed in order to allow someone else to consume resources. To give with a complete lack of selfishness is to be, rationally speaking, stupid.

The only sensible form of giving is that which is calculated expecting more in return. Lending with interest is a sensible and healthy form of giving which benefits the giver as well as the givee.

Smile Train is an apparently nice and effectively run charity that helps children with cleft lips. By donating $250, you can fix the cleft lip of one kid.

But if the parents of children with cleft lips aren't willing or able to invest $250 in a better life for their offspring, why should you help promote their genes?

You might be able to justify the gift if you expect the kid to repay you as an adult; either directly, if you give them the gift as a loan; or indirectly, by your gift increasing their ability to contribute in the economy in such a way that you yourself will benefit substantially from their increased contribution.

But more often than not, gifts tend to hurt their recipients. See the Spiegel interview with James Shikwati, an African economist: "For god's sake, please stop the aid!"

For the most part, gifts with no strings attached only serve to perpetuate a parasitic rather than a symbiotic relationship. Loans encourage symbiosis; you can take in a time of need, but when you can, you need to give a bit more in return.

Unrestricted giving, however, encourages parasitism. You can take; and you can take. And you can take. See the pattern?

For the most part, uncalculated altruistic giving is not only stupid, because it hurts you; it's evil, because it allows a parasitic pattern to proliferate, allowing it to hurt others.

Think hard before you give. Don't think only about someone's urgent need. Think about how your gift reduces their risks for doing something damaging, and increases their incentive for repeating it, or increases the incentive for others to do it in the future. Think whether your gift is really one-time, or whether it perpetuates a destructive pattern.

If in doubt - do not give.

Update. Here's an example of a Whole Foods store apparently unselfishly giving away groceries while experiencing a technical glitch. This sort of behavior makes sense. But there's a thin line between smart giving and stupid giving in cases like these. Notice that there was no announcement of the freebies, and the situation lasted only a short while. This makes sure that the free groceries were given only to unsuspecting customers - people who didn't come with the intention of taking advantage, and are likely to reward the store for its largesse by shopping there in the future more frequently. Imagine now that the store announced that groceries are free, or that the situation lasted long enough for people to alert their friends to take advantage. What would be the consequences for the store then?

Now, knowing this, answer the rhetorical question posed somewhat stupidly by the article's author: "Imagine the kind of world we would live in if all corporations were run like Whole Foods." Indeed? Stores consistently giving away stuff below market price - what would that lead to?

Overconsumption? Queues? Shortages? Black markets?
