The non-partisan Congressional Budget Office in Washington, DC recently released a report that gives evidence that not only are the rich are getting richer, but the gap between the very rich and the rest of us is expanding more now than any time in our history.
The upper 1% of the population saw its income increase by 275% between 1979 and 2007. The middle income earner saw an increase of 40% in that period, while the bottom 20% saw an increase of 18%. The wealthiest 1% of the population managed to take control of about 25% of all the income increases in the US during that period.
