I read this article in GOOD that pointed towards this paper - I recommend both. It's worth really looking at and thinking about the implications of this. The basic takeaway from this is that the bottom 60% of the US populace has no stake in our country, the top 20% for all intents and purposes - own everything, and even rich republican men think the world should be more fair than it is.
Sweden seems to be doing just fine. I'd really like to see this study done throughout the world and within even more specific groups of people - by age, by neighborhood in Chicago, by education, etc.
And yet the Right and even members of economic academia that are pushing for tax cuts for the rich. Deeply troubling and disturbing is an understatement.
The percentage present between the pie charts is explained in the paper. When shown two of the charts unlabeled (didn't know what country it represented) at the same time Americans preferred the Swedish income distribution to our actual distribution. Americans also preferred the Swedish chart to perfect distribution - which in and of itself is fascinating if not surprising.
