Income inequality isnt just desirable (within reason), but unavoidable. The drive to get as many people as possible into a pack of absolute equals (as defined by equality of outcome, rather than equality of opportunity) only makes more people poor. The current example is the demand of fast food workers that they should make $15 an hour. I want to be sympathetic (it is blamed HARD to live on 8.50 an hour no matter how many hours you work), but demanding a wage that the market really won't sustain because the wage the market will sustain isn't really enough to live on only hurts the poor. Why? Because the poor who need those jobs as a stepping stone to better jobs (especially young people who, if not gainfully employed, may get bored and end up in gangs) will watch as those jobs vanish and are replaced by automated ordering stations and robotic burger flippers (both of which already exist and are on the market). And even if you could somehow force McDonalds not to fire people to accommodate a $15 minimum wage, the next thing that would happen would be that the price of McDonalds' food would go up...and the poor folks who have to eat a lot of fast food because it maximizes your bang for buck will suddenly find that, though their salaries are higher, they're no better off because so are their food bills.
