"The United States is becoming even more unequal as income becomes more concentrated among the most affluent Americans. Income inequality has been rising since the late 1970s, and now rests at a level not seen since the Gilded Age—roughly 1870 to 1900, a period in U.S. history defined by the contrast between the excesses of the super-rich and the squalor of the poor. Early in the twentieth century, the share of total national income drawn by the top 1 percent of U.S. earners hovered around 18 percent. That share hit an all-time high in 1928—when top earners took home 21.1 percent of all income, including capital gains—then dropped steadily through the next three decades. Amid the post-World War II boom in higher education, and overall economic growth, the American middle class swelled and prospered, and the top 1 percent of earners took home less than 10 percent of all income through the 1960s and 1970s. Since then, the topmost 1 percent have seen their share rise again: it shot past 15 percent in 1996 and crested at 20.3 percent in 2006, the most recent year for which numbers are available."
