How is the "Real Housewives" series connected to wall street?

I believe that reality shows are definitely linked to wall street. Before realty shows, all the things we see, from the cars driven to the clothes the actors wore were all staged. As a result we as Americans never thought deeply into the fact that we could acquire the things used on these shows mostly because we knew it was staged and the people were actors. Now Realty shows come and we are looking at the actual lives of these individuals, we refrain from calling them actors because we assume that what we see is real. Many of us know that at least some things are staged. The staging part uses product placements and even making an aired show around a particular product. This makes the product more accessible to the audience. We then go out and buy these products because we think, if Jill or Bethany can wear or drive this type of car, then I should do it too, especially if they look good doing it. Let me know your thoughts on this topic.
