Regarding income inequality, I recommend listening to some of the speeches/debates with Bernie Sanders.
E.g. he argues that the greatest receiver of welfare in the US is the wal-Mart family, because they get even richer paying their workers so little that the workers have to live on welfare. (In other words the welfare is "paying" the workers so that Wal-Mart don't have to.) He proposes to rise the minimum wage.
