The first step to fixing a problem is acknowledging you have a problem ....

If the Joe the Plumber wants to support tax cuts for the rich and he's fully aware of his situation, then there is no issue having that opinion. But if his self-image is distorted (as was implied by the media reports), then it is bad to posses that as it means you will be making wrong decisions based on incorrect understandings.

The issue isn't his desire to aspire to greater wealth, it's his unrealistic understanding of what his actual financial status is.
