The Real Housewives

Today as I was cleaning my house AGAIN I got to thinking about something. How come when I watch my weekly dosage of reality TV, mainly "The Real Housewives" or  random "Wives" of this or that, I never see them doing the endless routine of cleaning that I do on a daily basis. Now I'm not saying none of them do house work, but if you're going to say a show is about the daily lives of a stay at home wife, or wife in general, let's really get real. I have yet to see  anyone from  Basketball Wives dust a bookshelf, push  a swiffer, nor less even empty a dishwasher. I wonder if any of the Real Housewives even do any of their laundry? If so, why isn't anyone showing this?
