Over the last three decades, the pretax incomes of the wealthiest households have risen far more than they have for other households, while the tax rates for top earners have fallen more than they have for others, according to theCongressional Budget Office.

As a result, the average post-tax income of the top 1 percent of households has jumped by roughly $1 million since 1979, adjusted for inflation, to $1.4 million. Pay for most families has risen only slightly faster than inflation.

Before becoming Mr. Obama’s top economic adviser, Lawrence H. Summers liked to tell a hypothetical story to distill the trend. The increase in inequality, Mr. Summers would say, meant that each family in the bottom 80 percent of the income distribution was effectively sending a $10,000 check, every year, to the top 1 percent of earners.

Mr. Obama’s budget reflects that sensibility. Budget experts were still sorting through the details on Thursday, but it appeared that various tax cuts and credits aimed at the middle class and the poor would increase the take-home pay of the median household by roughly $800.

The tax increases on the top 1 percent, meanwhile, will most likely cost them $100,000 a year.

“The tax code will become more progressive, with relatively higher rates on the rich and relatively lower rates on the middle class and poor,” said Roberton Williams, a senior fellow at the Tax Policy Center in Washington. ..
