People are being sold, and buying, the idea that unlimited happiness is a fundamental right (as long as they have internet access, mobile phones, ipods, dvd players, anti-perspirants, and the right brands of sanitary towel) and if they don't have unlimited happiness there must be something wrong with them. Clinical depression is a real and terrible thing but many people who claim to have depression don't have depression, they're just unhappy. The ability to deal with unhappiness as a normal, temporary, part of life seems to have disappeared in the better-off countries within the last generation or two.
