ACA or Obamacare:  According to Huffington Post (by Kevin Short, 3/5/2014), Obamacare is "actually putting money in Americans' pockets...it was responsible for about three-quarters of a surprising January rise in U.S. consumer spending and American income growth."

Why?  

1.  "It expanded the Medicaid program...adding up to a $19 billion dollars in benefits in January."
2.  "...health care enrollees additionally received another $15 billion in the form of tax credits..."

Result:

These changes "freed up many Americans to spend money that would have gone towards health care premiums on goods and services instead."
