Here's a later study from different authors that replicates but also refines these findings: https://psycnet.apa.org/doiLanding?doi=10.1037%2Fpspi0000008 https://psycnet.apa.org/doiLanding?doi=10.1037%2Fpspi0000008 > Replicating past work, social class positively predicted unethical behavior; however, this relationship was only observed when that behavior was self-beneficial. When unethical behavior was performed to benefit others, social class negatively predicted unethical behavior; lower class individuals were more likely than upper class individuals to engage in unethical behavior. Overall, social class predicts people’s tendency to behave selfishly, rather than predicting unethical behavior per se.
