Well, there are several things: A) You can't be FORTUNATE without the existence of the misfortunate to make your situation so good; the forever alones make the non-forever alones feel a lot better about themselves because they aren't one of us B) we are a good cash source: who else buys "100 Magical Tips To Not Die Alone" books, articles and DVD's? Who else pays for online dating subscriptions, or speed dating meetups? C) They look at the use of Forever Alones from a Malthusian perspective: if we didn't stay alone forever, we might breed and add to population strain (and genetic dilution when thinking about the genetic pool).
Forever Alones are an economic boon, just like the obese and overweight.
