In 1928, the top 1% of families received 23.9% of all pretax income, while the bottom 90% received 50.7%. But the Depression and World War II dramatically reshaped the nation’s income distribution: By 1944 the top 1%’s share was down to 11.3%, while the bottom 90% were receiving 67.5%, levels that would remain more or less constant for the next three decades.

But starting in the mid- to late 1970s, the uppermost tier’s income share began rising dramatically, while that of the bottom 90% started to fall. The top 1% took heavy hits from the dot-com crash and the Great Recession but recovered fairly quickly: Saez’s preliminary estimates for 2012 (which will be updated next month) have that group receiving nearly 22.5% of all pretax income, while the bottom 90%’s share is below 50% for the first time ever (49.6%, to be precise).
