As Baby Boomers age, the demand for home health care aides is expected to explode, growing 70 percent between 2010 and 2020, according to the U.S. Labor Department. That makes it the single fastest growing job category in the United States, according to the department's forecasts, CNNMoney reported. 

Call it the silver tsunami. Roughly every eight seconds, a Baby Boomer turns 65. And that has led to surging demand for in-home care.

"This isn't just a surge, a one-time hiring spurt. This is something we will do this year and into the future," said Paul Hogan, chairman of Home Instead Senior Care, which alone plans to hire 45,000 caregivers in North America this year. "It's all driven by the growth in the senior population."

But even though there are plenty of job opportunities, many of these people make the same wage as teenagers flipping burgers or selling clothes at the mall. The average hourly wage is just $9.70 an hour, according to the Labor Department.
