Agree or disagree: Krugman on Joe the plumber?

I agree. I haven't seen in the past 8 years much progress to the Working Americans, instead there were large tax cuts to large businesses America. What I don't understand is how people are saying that this guy Joe (Sam) has showed what Obama's true tax plan is. I still think taxing the rich is a great idea, it is time for them to share the pain like the rest of us, even if its "undermining the American Dream."
