Who argued that a new class in society called the nouveau riche was related to "creating the consumer"?

Richard Nellission

Explanation:

Nouveau riche is a term referring to a person who has managed to amass a considerable fortune during his life. The term is generally used to emphasize the fact that the individual was previously at a lower level on the scale of the social class, and whose new wealth has provided him with the means to acquire new luxuries that were previously impossible to obtain. According to Richard Nellisson, what better describes this new social class is the consumerism. Once they had emerged from a low-level class, they still don't know how to deal with the new social trends and economical aspects.
