PAY SCALE PAY SCALE Paychecks from private business shrank to their smallest share of personal income in U.S. history during the first quarter of this year, a USA TODAY analysis of government data finds. At the same time, government-provided benefits — from Social Security, unemployment insurance, food stamps and other programs — rose to a record high during the first three months of 2010. Those records reflect a long-term trend accelerated by the recession and the federal stimulus program to counteract the downturn. The result is a major shift in the source of personal income from private wages to government programs. The trend is not sustainable, says University of Michigan economist Donald Grimes. Reason: The federal government depends on private wages to generate income taxes to pay for its ever-more-expensive programs. Government-generated income is taxed at lower rates or not at all, he says. "This is really important," Grimes says.

Even before the downturn, private wages were eroding because of the substitution of health and pension benefits for taxable salaries. The Bureau of Economic Analysis reports that individuals received income from all sources — wages, investments, food stamps, etc. — at a $12.2 trillion annual rate in the first quarter. Key shifts in income this year: • Private wages. A record-low 41.9% of the nation's personal income came from private wages and salaries in the first quarter, down from 44.6% when the recession began in December 2007. •Government benefits. Individuals got 17.9% of their income from government programs in the first quarter, up from 14.2% when the recession started. Programs for the elderly, the poor and the unemployed all grew in cost and importance. An additional 9.8% of personal income was paid as wages to government employees. The shift in income shows that the federal government's stimulus efforts have been effective, says Paul Van de Water, an economist at the liberal Center on Budget and Policy Priorities. "It's the system working as it should," Van de Water says. Government is stimulating growth and helping people in need, he says. As the economy recovers, private wages will rebound, he says. Economist Veronique de Rugy of the free-market Mercatus Center at George Mason University says the riots in Greece over cutting benefits to close a huge budget deficit are a warning about unsustainable income programs. Economist David Henderson of the conservative Hoover Institution says a shift from private wages to government benefits saps the economy of dynamism. "People are paid for being rather than for producing," he says. Guidelines: You share in the USA TODAY community, so please keep your comments smart and civil.
