Arguing against suicide, a correspondent writes:
By choosing to live one can prevent much more suffering than by killing oneself (hundreds or thousands times more!). Everyone who thinks about suicide knows how horrible suffering can be (and therefore should know how important it is to prevent as much of it as possible). I agree that it is better not to be born at all, but now that we are alive, we have the choice. If I kill myself I can spare myself some amount of suffering, but if I choose to live and dedicate my life to helping others I can spare them hundreds or thousands times more suffering.
I have previously indicated that one of the reasons I have not committed suicide to date is that I know my death would cause considerable pain to others. But this made me wonder: what is, in fact, the net effect of suicide?
Actually, it turns out that suicides are probably on balance good for society. A 2007 study found that considering all the economic impacts of suicide, the 30,906 suicides completed in 1990 actually saved the United States $5.07 billion - in 2005 dollars (about $160,000 per suicide). That's right - suicides, on balance, represent an economic gain for society.
What about the environment? An American produces about 20 tons of carbon dioxide per year. A 33-year-old female like me, with 50+ years left of her natural lifespan, could presumably prevent 1000 tons of carbon dioxide from reaching the atmosphere by packing it in early.
That is not to mention the many other harmful effects that people, particularly first-world people, have on the environment and its inhabitants.
I have argued that the possibility of doing good for others is extremely limited, partially by what I term the altruistic treadmill. I am highly skeptical of the claim that a person can sustainably increase the well-being of other people. (See, e.g., Lykken and Tellegen's "Happiness is a Stochastic Phenomenon.") I suspect that a real-life It's a Wonderful Life would be much more ambivalent than the theatrical version. At any rate, such an increase in well-being would have to outweigh the concrete, measurable gains to society from ending one's life - $160,000, a thousand tons of carbon dioxide, and one less mouth to feed - not to mention never, ever again triggering an ostracism response in another human being, nor hurting anyone or anything again, ever.
You would have to be a pretty stellar human being to make up for that. I'm mostly speaking for myself here, but I doubt most people who have gotten to the point of considering suicide have the capacity to drastically improve the lives of others in a sustainable way, to reach a magnitude large enough to offset the very real gains to society that their suicides would entail.
Also: this is probably the point where I should get the hell off of blogspot before they delete all my shit.
