It as reported that monkeys have a sense of justice. Scientists constructed an experiment whereby monkeys were given tokens, which they could exchange for food after performing special tasks. They were rewarded with either cucumber or grapes. Monkeys merely like cucumber, but absolutely love grapes.
When the monkeys who had performed exactly the same task dutifully handed in their tokens and all were equally apportioned either cucumber or grapes, peace reigned within society. But if some were given cucumber and others grapes after having performed precisely the same tasks, the shit hit the fan. Some refused to eat their reward, some tossed it away indignantly. Next time round after having put in an honest day’s work, and the same thing happened, some even refused any reward. After a while, some refused to work.
But never did they show any animosity, jealousy or aggression towards each other. Their disgust at this horrendously unjust distribution of cucumbers and grapes was directly solely at their employers. Marx and Engels would rejoice at this confirmation of their thesis.
