I think it’s also important to understand why the distribution of income changed in the 1970s. It’s not enough to say that the rewards have flowed to those at the top because of their increased contribution to society, as productivity has risen since the 1970s workers have contributed more, but their compensation has not increased commensurately. My own belief is that changes in economic power and the political power that comes with it have distorted income flows and changed the rules of the game in a way that favors those at the top. Thus, it’s not that those at the top deserve what they have received because of their contributions, though perhpas it’s partly that, it’s also due to a change in the way income is distributed arising from changes in economic/political power.
You can’t quantify emotions; fear, loathing, objectivism etc. But it can hardly be described as good policy or economics if the best one can hope for is to work enough hours to stick their noses above the poverty level.
