A business degree and a decade of negotiating information technology contracts didn't prepare Denise Sjoberg for workdays changing diapers, comforting crying toddlers and negotiating nap times.
But then, she's not the only middle-class American adapting in tough times.
Sjoberg, who holds an MBA, was laid off in 2009. When the 49-year-old mother of three teenagers couldn't find a job in her profession, she opened a licensed day-care center out of her home in Eagan.
Today, she makes $13,000 less per year, thinks twice before going out to eat and won't take a big vacation any time soon. "You don't compare what you had with what you're going to have next," Sjoberg said.
Across the country, household incomes have been falling for a decade, a dip accelerated by the Great Recession and profoundly felt by the middle class. From 2007 to 2010, the median household yearly income in Minnesota dropped 14 percent from $61,051 to $52,554. Nationwide, it fell from $52,823 to $49,445.
The recession upended a fundamental assumption of middle-class life -- the belief that most working families can count on earning a little more than the year before.
"All of those rules you had about how the world operates, they're all gone," said Tom Gillaspy, Minnesota's demographer.
The 8 million jobs lost to the recession cemented a decade of declining income. Roughly 60 percent of job losses fell disproportionately on mid-wage hourly positions, according to the National Employment Law Project.
