Payback: Debt and the Shadow Side of Wealth
by Margaret Atwood
Published 15 Mar 2007

Atwood, for sending me various articles on epigenetics. There are many variants to the “Punch-buggy, no punch-backs” game. In one, the colour of the Beetle must be specified. I leave it to the experts to dispute the many rules. For primate trading, see De Waal, Frans, and S. F. Brosnan. “Monkeys Reject Unequal Pay.” Nature (2003): 425.

The Growth Delusion: Wealth, Poverty, and the Well-Being of Nations
by David Pilling
Published 30 Jan 2018

They now enjoy a bigger slice of America’s economic pie than their counterparts did in the so-called Gilded Age of the late nineteenth century.6 If your country’s economy is growing solely because the rich are getting richer and if you are working harder and harder just to maintain your living standard, then you are entitled to ask what, precisely, is all this growth for? That is particularly true since study after study shows that people’s happiness depends not on their absolute wealth, but rather on their wealth relative to those around them. In an experiment written up in a paper called “Monkeys Reject Unequal Pay” two capuchin monkeys were initially perfectly content with a reward of cucumbers when they successfully performed a task. But when one monkey was subsequently given tastier grapes as a reward, the monkey receiving plain old cucumbers became enraged, angrily flinging the previously satisfactory salad vegetable at its handler.7 The monkeys’ economy had grown, since grapes are better than cucumbers.

Inequality and the 1%
by Danny Dorling
Published 6 Oct 2014

And it is not just us. A paper was published in Nature in 2003 concerning experiments with monkeys being fed with cucumbers, or preferably grapes, in which the monkeys rejected being rewarded unequally, opting for no reward rather than an unfair one.

Behave: The Biology of Humans at Our Best and Worst
by Robert M. Sapolsky
Published 1 May 2017

But monkey 2 gets some cucumber, which blows compared with grapes—capuchins prefer grapes to cucumber 90 percent of the time. Monkey 2 was shortchanged. And monkey 2 would then typically fling the cucumber at the human or bash around in frustration. Most consistently, they wouldn’t give the pebble the next time. As the Nature paper was entitled, “Monkeys reject unequal pay.” This response has since been demonstrated in various macaque monkey species, crows, ravens, and dogs (where the dog’s “work” would be shaking her paw).*13 Subsequent work by Brosnan, de Waal, and others fleshed out this phenomenon further:14 One criticism of the original study was that maybe capuchins refused to work for cucumbers because grapes were visible, regardless of whether the other guy was getting paid in grapes.
