What is Affluenza?

Legal Definition
Affluenza, a portmanteau of affluence and influenza, is a term used by critics of consumerism. It is thought to have been first used in 1954 but it gained legs as a concept with a 1997 PBS documentary of the same name and the subsequent book, Affluenza: The All-Consuming Epidemic (2001, revised in 2005, 2014). These works define affluenza as "a painful, contagious, socially transmitted condition of overload, debt, anxiety, and waste resulting from the dogged pursuit of more". The term "affluenza" has also been used to refer to an inability to understand the consequences of one's actions because of financial privilege, notably in the case of Ethan Couch.
