In a speech in Washington on Thursday, the chairman of President Obama’s Council of Economic Advisers said that the American middle class has been shrinking since 1970. Princeton University economist Alan Krueger said the American middle class shrank from 50.3 percent of American households in 1970 to 42.2 percent in 2010. Krueger defined the middle class as households with annual incomes within 50 percent of the national median income. Here is a table presented describing his findings.
On Tuesday, Barack Obama declared the debate over how to restore growth, balance, and fairness to the American economy the “defining issue of our time.”
For two hundred years, the middle class has enjoyed legendary status in Western economic thought. First the British and then the American middle classes, Weber, Marx and many others said, served as vaunted engines of economic growth and political stability throughout the 19th and 20th centuries.
