I'll say it for the 120,465th time this week. Obama promised to raise the minimum wage every year and didn't even try it once in 4 years. If the democrats thought people were enslaved by their wages, they could have fixed it. They did not.
As for the tortuous reading of the Constitution by the left, they forget the 10th Amendment:
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." (emphasis added by a Jeffersonian Democrat)
