Walt Whitman says, 'everyone has a dream'

I think Whitman is expressing that everyone has 'an American dream,' from the shoemaker to the mason, from the carpenter to the mechanic, everyone dreams and sings about their life in American! He expresses that people make it to the American Dream by working hard at what he or she does best.
I think his point of view on the American Dream is the most accurate I have read about so far. He's got it right, you have to work hard at what your good at and sing while you're doing it, to get to where you want to go.
