| "It's likely that when we are all working for a living and prospering then we all prosper a little more." Well, of course, we all prosper when we all are prospering. :) While life isn't exactly a zero-sum game, for certain moments it works that way. In any case, for now (nearly) all of us are Earth-bounded, so the limits of what our planet and our Sun can provide to us (over time) is what truly matters. There's only so much of Earth to go around, and only so much radiation to be received from the Sun. (And I am of course overlooking the occasional changes from meteors and comets and other whatnot from the heavens.) This thing about income (and wealth) inequality is about more than mere discontents. There are plenty who fear that our global economic system (leaning heavily on capitalism with sprinkles of socialism) will soon arrive at a point of being unsustainable - a point that arrives prior to actual resource depletion. The heart of it is in the ways that people can be so entitled to things, such as water, food, clothing, shelter, education, offspring, healthcare, etc. The worries are about the consequences of greater portions of the population being at or below subsistence levels. This is especially alarming when the statistics show it growing more significant within "First-World" nations. The three big factors seem to be (to me, anyway): (1) Strong property rights which enables more rentiers and natural monopolies; (2) Rentiers/Monopolizers out-competing most or all others for political and economic influences and favors; (3) human labor becoming less needed over time due to the growing rise of adaptable and reliable automation. The automation of item 3 would make a "Galt's Gulch" more tenable, but it would probably be realized as an artificial island nation. Well, one can dream of one, anyway (see http://theweek.com/articles/482427/libertarian-island-billio...). One can easily google on "wealth inequality" and get some sober/reasonable/academic reads on this. A good primer is at https://www.washingtonpost.com/news/wonk/wp/2015/05/21/the-t....
