Who usually owns a plumbing company?

It seems the media thinks that plumbing companies are not own by someone who worked as a plumber. I think it is just the opposite. Most likely the president of a plumbing company was a plumber himself. They reference Joe the Plumber and point out that he doesn't make $200K a year. He never said he did. He said he was wanting to buy the plumbing company he worked for. Obama even made fun to him saying he never knew a plumber that made $200K. Joe never said he made $200K but if he bought the company he hoped to make $200K and more. Does the media think we should be ashamed to aspire to make more than we are currently making or is it just a lame attempt by them to make Joe look like a liar so we will ignore Obama's comment that his goal was one of creating a country that spreads the wealth around... like is done for welfare recipients? I think saving the elite embarrassment, such as Obama, at the expense of the middle class, such as Joe, doesn't make him any less of a citizen or respected.
