You can find many philosophy papers on the themes of 'love' and 'friendship,' most of which are cheerful and somewhat anodyne; you don't find many on the loss of friends, relatives, and lovers from death or alienation, though it happens all the time.

People's wants are not fixed; they generally want what others in their chosen comparison class appear to be enjoying and what advertising presents to them as attainable for them and as bringing happiness.
