Who Rules America: Wealth, Income, and Power
Some of the highlights:
* The top 5% of income earners control 62% of the country's net wealth;

80% of income earners control only
15% of the country's net wealth;
* The top 5% control 72% of the country's financial wealth;
* The top 10% control virtually all of the financial wealth;
* The top 1% control 43% of the financial wealth;
