JoAnne, the Plumber’s Receptionist

Sorry I’m stating the obvious, but something was missing from that debate.
All the fuss about “Joe the Plumber,” but no one seems concerned with “JoAnne, the Plumber’s Receptionist.” (Let’s just fictionalize “Joe” for argument’s sake, as I do not wish to assume what he, personally, would do if he were able to buy the business he wants.)
The candidates fussed over details of just how much money “Joe” would have to make before his taxes would increase. (I believe under Obama’s plan, it was around 250k per year.) If “Joe’s” business is booming, he may have to hire a receptionist to handle the phones, set up appointments. Forgive the gender stereotyping, but most receptionists I know are women — of course, they are women with real bills to pay, just like “Joe.”
The minimum wage in Ohio is $7 per hour. A quick Google indicates a receptionist in Ohio might earn more like $9 or $10 per hour.
If working full-time, $10 per hour will gross you $20,000 per year.
How will “JoAnne the Receptionist” save for a down payment on a house? Pay off student loans? Support her children? How will she pay her medical bills if she gets sick? McCain’s 5,000 bucks he wants to provide for health care will be gone after one or two tests.
