WASHINGTON (AP) -- Four out of 5 U.S. adults struggle with joblessness, near-poverty or reliance on welfare for at least parts of their lives, a sign of deteriorating economic security and an elusive American dream.

Survey data exclusive to The Associated Press points to an increasingly globalized U.S. economy, the widening gap between rich and poor, and the loss of good-paying manufacturing jobs as reasons for the trend.

The findings come as President Barack Obama tries to renew his administration's emphasis on the economy, saying in recent speeches that his highest priority is to "rebuild ladders of opportunity" and reverse income inequality.

As nonwhites approach a numerical majority in the U.S., one question is how public programs to lift the disadvantaged should be best focused — on the affirmative action that historically has tried to eliminate the racial barriers seen as the major impediment to economic equality, or simply on improving socioeconomic status for all, regardless of race.

Hardship is particularly growing among whites, based on several measures. Pessimism among that racial group about their families' economic futures has climbed to the highest point since at least 1987. In the most recent AP-GfK poll, 63 percent of whites called the economy "poor."

"I think it's going to get worse," said Irene Salyers, 52, of Buchanan County, Va., a declining coal region in Appalachia. Married and divorced three times, Salyers now helps run a fruit and vegetable stand with her boyfriend but it doesn't generate much income. They live mostly off government disability checks.

"If you do try to go apply for a job, they're not hiring people, and they're not paying that much to even go to work," she said. Children, she said, have "nothing better to do than to get on drugs."

While racial and ethnic minorities are more likely to live in poverty, race disparities in the poverty rate have narrowed substantially since the 1970s, census data show. Economic insecurity among whites also is more pervasive than is shown in the government's poverty data, engulfing more than 76 percent of white adults by the time they turn 60, according to a new economic gauge being published next year by the Oxford University Press.

The gauge defines "economic insecurity" as a year or more of periodic joblessness, reliance on government aid such as food stamps or income below 150 percent of the poverty line. Measured across all races, the risk of economic insecurity rises to 79 percent.

Marriage rates are in decline across all races, and the number of white mother-headed households living in poverty has risen to the level of black ones.

"It's time that America comes to understand that many of the nation's biggest disparities, from education and life expectancy to poverty, are increasingly due to economic class position," said William Julius Wilson, a Harvard professor who specializes in race and poverty. He noted that despite continuing economic difficulties, minorities have more optimism about the future after Obama's election, while struggling whites do not.

"There is the real possibility that white alienation will increase if steps are not taken to highlight and address inequality on a broad front," Wilson said.

Nationwide, the count of America's poor remains stuck at a record number: 46.2 million, or 15 percent of the population, due in part to lingering high unemployment following the recession. While poverty rates for blacks and Hispanics are nearly three times higher, by absolute numbers the predominant face of the poor is white.

More than 19 million whites fall below the poverty line of $23,021 for a family of four, accounting for more than 41 percent of the nation's destitute, nearly double the number of poor blacks.

Sometimes termed "the invisible poor" by demographers, lower-income whites generally are dispersed in suburbs as well as small rural towns, where more than 60 percent of the poor are white. Concentrated in Appalachia in the East, they are numerous in the industrial Midwest and spread across America's heartland, from Missouri, Arkansas and Oklahoma up through the Great Plains.

Buchanan County, in southwest Virginia, is among the nation's most destitute based on median income, with poverty hovering at 24 percent. The county is mostly white, as are 99 percent of its poor.
