Avery Weltschmerz. The investment guru Jim Cramer used it in the same sentence as Schadenfreude, though I forget the context.
These are concepts that have (in a way) opposite meanings. "Schadenfreude" (literally "shameful joy") is the joy of someone else's failure. "Weltschmerz" ("pain of the world") is a set of moods and emotions such as: depression, sadness, apathy, melancholy resulting from thoughts about the imperfection of the world, or rather from the clash of the will to act and the inability to implement it, and the dissonance between the hero's sensitivity and his environment. In other words, romantic, sentimental pessimism.
