A boomer lives on $2,600 monthly from Social Security and his Walmart job: 'If I had $1 million, I don't know what I would do with it.'

• George Dziamniski, 62, lives on Social Security and a Walmart paycheck in Pennsylvania.
• He lives simply and avoids the need for extensive retirement savings, he said. 
• But many older adults have an income near the federal poverty line and aren't sure they can retire.

George Dziamniski, 62, said he doesn't need much.

He works two or three days a week at a Walmart warehouse and cashes his monthly Social Security check, which he said is enough to finance his "simple" lifestyle. He has no retirement savings, but he isn't worried.
