>> “Undank ist der Welten Lohn”. > I couldn't find a common translation or appearance of this saying's equivalent in English. Ungratefulness is the world's wage? I believe it means something akin to "nothing is so hard as man's ingratitude." It's an expression that's not dissimilar to "no good deed goes unpunished." They're not quite the same, but they're tandem in the general principle of ingratitude.
