In the article Progressive Taxation and the Subjective Well-Being of Nations it would seem as if there is some correlation between progressive taxation and subjective well-being.
Using data from the Gallup World Poll, we examined whether progressive taxation is associated with increased levels of subjective well-being. Consistent with Rawls’s theory of justice, our results showed that progressive taxation was positively associated with the subjective well-being of nations.
What I would like to know is who is this Rawl, and how can he be quoted so out of context that it makes me cringe?
