"Wealth has become even more concentrated during the Bush years. Today, the richest one percent of Americans has 22 percent of all income and about 40 percent of all wealth. This is the biggest concentration of income and wealth since 1928. In 2005, average CEO pay was 369 times that of the average worker, compared with 131 times in 1993 and 36 times in 1976. At the pinnacle of America’s economic pyramid, the nation’s 400 billionaires own 1.25 trillion dollars in total net worth - the same amount as the 56 million American families at the bottom half of wealth distribution."
