Over the last three decades the wealth of the nation's very richest 1% has grown ten times that of the average worker and over that time period that same tiny elite has captured more than half of the entire income increases, leaving the bottom 99% to divide the remaining gains.

This is all based on a new state-level study, The Increasingly Unequal States of America: Income Inequality by State, which looks at how inequality has seized hold of the national economy both in the generation leading up to the great recession of 2008 and in the several years following where a so-called "recovery" was experienced by the financial elite while the majority of U.S. population continues to claw its way back.

“The levels of inequality we are seeing across the country provide more proof that the economy is not working for the vast majority of Americans and has not for decades,” said Mark Price, an economist at the Keystone Research Center, who co-authored the report on behalf of the Economic Analysis and Research Network (EARN). “It is unconscionable that most of America’s families have shared in so little of the country’s prosperity over the last several decades.”

Numerous studies in recent years have exposed the persistent pattern of income and wealth inequality in the United States, but as Price's co-author Estelle Sommeiller explains, “our study shows that this one percent economy is not just a national story but is evident in every state, and every region.”

Though some states show higher levels of inequality, the pattern nationally is firm. What is also made clear by the study is the degree to which specific policies--including the writing of tax law, the climate set for labor conditions, and the setting of wages--have all contributed directly to this pattern where those at the very top benefit from a growing economy and those at the bottom receive increasingly less reward for their hard work.

“It’s clear that policies were set to favor the one percent and those policies can, and should, be changed,” Doug Hall, director of the EARN program said. “In order to have widespread income growth, bold policies need to be enacted to increase the minimum wage, create low levels of unemployment, and strengthen the rights of workers to organize.”

Among the report's key findings:

• In four states (Nevada, Wyoming, Michigan, and Alaska), only the top 1 percent experienced rising incomes between 1979 and 2007, and the average income of the bottom 99 percent fell.
• In another 15 states the top 1 percent captured between half and 84 percent of all income growth between 1979 and 2007. Those states are Arizona (where 84.2 percent of all income growth was captured by the top 1 percent), Oregon (81.8 percent), New Mexico (72.6 percent), Hawaii (70.9 percent), Florida (68.9 percent), New York (67.6 percent), Illinois (64.9 percent), Connecticut (63.9 percent), California (62.4 percent), Washington (59.1 percent), Texas (55.3 percent), Montana (55.2 percent), Utah (54.1 percent), South Carolina (54.0 percent), and West Virginia (53.3 percent).

• In the 10 states in which the top 1 percent captured the smallest share of income growth, the top 1 percent captured between about a quarter and just over a third of all income growth. Those states are Louisiana (where 25.6 percent of all income growth was captured by the top 1 percent), Virginia (29.5 percent), Iowa (29.8 percent), Mississippi (29.8 percent), Maine (30.5 percent), Rhode Island (32.6 percent), Nebraska (33.5 percent), Maryland (33.6 percent), Arkansas (34.0 percent), and North Dakota (34.2 percent).
