According to Business Week, a Report of a 20-year study conducted by the international Organization for Economic Cooperation and Development on income and wealth disparity in its member countries confirms that
The United States has the highest inequality and poverty in the OECD after Mexico and Turkey, and the gap has increased rapidly since 2000,
In the US, the richest 10% of the population earn an average of $93,000 -- the highest level in the OECD, and hold 71% of the wealth, while the poorest 10% earn an average of $5,800, which is 20% percent lower than the average for OECD countries.
Some of the Report's other findings are that "rich households in America have been leaving both middle and poorer income groups behind and that the effect of taxes and government transfers on reducing inequality has fallen in the past 10 years. Not surprising, since US spending on family and social benefits is only at a level of 9% of family income, while the OECD average is 22%.
But at least we are ahead of Turkey.
