The utility monster is a thought experiment in the study of ethics created by philosopher Robert Nozick in 1974 as a criticism of utilitarianism.
[citation needed] Robert Nozick, a twentieth century American philosopher, coined the term "utility monster" in response to Jeremy Bentham's philosophy of utilitarianism.
[citation needed] Nozick deems these exploiters "utility monsters" (and for ease of understanding, they might also be thought of as "happiness hogs").
Nozick poses that utility monsters justify their greediness with the idea or feeling that, compared to others, being in the world inflicts greater inequality or sadness on them, and therefore they deserve more happy units to bridge this gap.
Utility monsters would state that the others are happier in the world to begin with, so they do not need the "extra" happy units they would like to lay claim to.
