I really don't see how you get that out of helping the middle class. It seems like what she means is she wants to extend help to the middle class as well. Just improve social welfare all around for everyone that needs it. Now if she will actually do that, that's up for debate.
I assumed because the headline had said 'Hillary's economic plan: raise middle-class incomes' rather than 'extend help to middle-class' the description being "Hillary has a plan to build a strong, growing economy that works for everyone—and it starts with raising incomes for hardworking Americans."
Very poor wording. Regardless the wording I somehow doubt she'll stick to it. Just a feeling.
I don't like Bernies plan of raising min wage to $15 seems a bit much. $9-10 would be just fine for the lower end. You're not suppose to make a living off of making McDoubles
