For Sue Spencer, a single mother of two in New Hampshire, paying the bills isn't always easy.
NPR reports she earns $42,000 a year, close to the nation's median income, assisting the elderly as a case manager.
She finds fulfillment in her job, but not enough money to provide for her two grown daughters as they head off to college.
"I love what I do," says the 50-year-old mother of two in Marlborough, N.H. "I am a case manager to the core. It makes me feel good. But I do regret that somewhere along the way, someone said, 'Here is how your job is valued.' [This is] the pay that went with my position."
Spencer's story is part of NPR's series "Living In The Middle" about the growing struggles of America's middle class.
