 One way to develop the deniers’ position is as  follows.[9]  Envy is a distinctive kind of psychological state that is essentially competitive. It is concerned specifically with unfavorable comparisons to others with whom the subject in some ways sees himself as in competition. On this view, the characteristic dissatisfaction of envy supplies or embodies some level of motivation toward whatever would ameliorate the situation: in other words, toward either outdoing or undoing the rival’s advantage Which of those motivations will emerge in action depends on many factors. It depends on what the situation affords, including the probabilities and expected costs and benefits of success at either option. And it depends on other attitudes and desires of the subject, including how much he likes the rival, whether he thinks it would be wrong to deprive him of the good, and how much that wrongness matters to him.
