capital
Explanation
This comic depicts a scene at the gates of Heaven, where St. Peter is explaining to a newly arrived soul that their algorithm led to more efficient allocation of capital, increasing gross domestic product in a way somewhat correlated with decreases in infant mortality rates. The person is making a tortured, jargon-heavy case for why their work in finance was morally good. St. Peter's response -- "It's more nuanced. See page 52, section C" -- satirizes how modern financial professionals justify their work through layers of abstraction and technicality. The soul asks St. Peter to explain it again from the beginning.
The caption delivers the punchline: "Of course, all the high speed traders go to Hell. St. Peter just likes to toy with them for a while." The joke is that St. Peter already knows these finance people are damned, but he enjoys letting them go through their elaborate self-justification speech before delivering the verdict. The humor works on multiple levels: it mocks the Byzantine rationalizations that people in high-frequency trading use to argue their work benefits society, and it imagines a God who finds the same amusement in their squirming that many regular people do. It also plays on the common moral intuition that extracting money from markets through speed advantages, rather than creating tangible value, is ethically suspect.
