One of the more interesting definitions of McMansions I encountered in my 2012 study involved the homes serving as a symbol of excessive consumption. Here is a recent example:

The survey shows—and it’s not even close—that the No. 1 way in which people define a good life is “having family and friends that love me.” The answer was nearly universal, cited by 94% of respondents. After this came “making a positive impact on society (75%). Having a high-powered job or bunking down each night in a McMansion might be nice, but in the end such things don’t mean that you’re loved or respected or that you’ve made your community a better place.
This finding is a common one: people at the end of life say relationships matter more than what they bought or consumed. For example, see the results of the Grant Study:
“When the study began, nobody cared about empathy or attachment. But the key to healthy aging is relationships, relationships, relationships,” Vaillant says. Close relationships, the data indicates, are what keep people happy throughout their lives. The study found strong relationships to be far and away the strongest predictor of life satisfaction, and better predictors of long and happy lives than social class, wealth, fame, IQ, or even genes. That finding proved true across the board among both the Harvard men and the inner-city participants.
Yet, the comparisons made to what really matters – relationships – are interesting as they target key markers of success in the United States. The first is a high-status job. Adults often define their worth and status by their job. Second is the home. In a country that idealizes owning a single-family home, this makes for a striking alternative to prioritizing people.
Why pick a McMansion here as opposed to a typical suburban single-family home? There could be several reasons. A McMansion is a particular symbol of success, a home whose facade tries to exude status. A McMansion is larger than a typical single-family home, usually coming in between 3,000 and 10,000 square feet. And, perhaps most important here, the McMansion is a symbol of the wrong kind of consumption. Owners are trying too hard with their home to show off. The home is poorly designed. Compared to life-giving relationships, the McMansion pales in comparison. Rather than think of people who are McMansion-rich but house poor, think of people who own a McMansion but have poor relationships…a furthering of a long-standing suburban plot where people look like they have achieved the American Dream but their lives are falling apart.
