Isn't it disingenuous to infer that this inclination should not imply anything about economic policy? I would arrive at the opposite conclusion. Economics are sentiment driven by a huge factor. Robert Shiller's work in behavioral economics and his book Irrational exuberance has established and popularized this idea. Krugman's discussion of the unsuitability of BitCoin as a currency rests largely on the peculiar nature of human sentiment and behavior. Large income gaps are perceived by most people as unfair irrespective of the contributions by the wealthy. No one thinks that Bill Gates/ Edison made a greater contribution to social progress than Einstein/Gandhi. I don't think the association of the net worth of an individual to the contribution that they have made to society is very strong. Economies rewards people largely on the basis of demand/supply with I believe is a weak proxy for social contributions.
Perhaps you want to draw an analogy to say gay marriage where the popular vote might end up denying gay rights, but I don't think a similar argument holds in the case of wealth distribution.
