Mises on how socialists wound the workers’ self-image:
This anticapitalist propaganda is a systematic scheme for the substitution of tedium for the joy of labor. …
The worker rejoices in his place in society and his active cooperation in its productive effort.
If one disparages this ideology and replaces it by another which represents the wage earner as the distressed victim of ruthless exploiters, one turns the joy of labor into a feeling of disgust and tedium. (HA, 590-1)
