The Gini index, which measures how income is distributed, reached 0.47 for 2011, its highest point in more than 40 years. The increase represented a 1.6 percentage leap from 2010 and the first statistically significant increase since 1993. What it really means is that the gap between the haves and have-nots is increasing. The index is set up so that a score of ’0′ means that our country’s wealth is distributed perfectly evenly; a score of ’1′ means that one individual is receiving all the income.
