Step-by-step explanation:
The Kardashians have presented themselves as an average American family by emphasizing scripted and relatable everyday challenges. While they do flaunt their wealth, such as buying sports cars and mansions, the show also attempts to connect with viewers through common family dynamics and personal issues that resonate with a broad audience. This balancing act allows viewers to see aspects of their lives that may appear relatable, despite their extraordinary wealth and lifestyle. This method of presentation is a common theme throughout various reality television shows, as they merge the spectacle of wealth with the familiarity of everyday struggles.
