With benefits factored in, workers' total compensation did outpace inflation in 2004, even if they didn't see it in their paychecks. But employers also are requiring workers to pay a greater share of their premiums.
"Healthcare has eroded the wage base," said Janemarie Mulvey, chief economist with the Employment Policy Foundation, a business-funded think tank in Washington.
"In the long run, we can't continue like this. If healthcare keeps crowding out wages forever, something's got to give."
The squeeze is especially intense on the 47% of the workforce whose employers don't directly provide their health insurance. For lower-income workers, who are more likely to be uninsured, the falling value of their wages is even more serious because they're more likely to live paycheck to paycheck. And rising food and energy prices take a proportionately higher toll on the poor than on the rich.
Historically, periods when wage growth is outpaced by inflation rarely last more than 18 months. That's partly because businesses don't want their employees' living standards to fall, as that injures morale, said Trewman Bewley, a Yale University economist who has studied wage activity during economic downturns.
Many economists figure it's only a matter of time until workers can pry more money out of their employers to catch up to inflation again. If economic growth remains robust, as many forecasters predict, workers may gain greater leverage to negotiate wage hikes.
"Chances are that those workers that have problems getting by because of higher fuel prices will probably tell their employers, 'I can't make it,' " said John Lonski, chief economist at Moody's Investors Service.
That hasn't played out for Brian Chartier. The 29-year-old Glendale resident handles inventory for a Los Angeles manufacturing company. No one there, he said, has gotten a raise in two years.
"They're able to do this and I haven't quit, because where am I going to go?" he said. "There are no jobs."
While his salary remained flat, rising healthcare premiums kept eating up more and more of Chartier's take-home pay, so he dropped out of his employer's insurance program. His rent is also climbing.
As Chartier loaded bags of groceries into his Honda Civic last week, he boasted that they were full of bargains. "I don't get a single thing that's not on sale," Chartier said. "I can't afford to anymore."
