For example, I bet you'd rarely see actual Venetian plaster in a McMansion, but you'd see a "faux finish" version of it. McMansions are movie sets and the owners are playing a "role" of a "successful" person/family.
Ah, I love that. Applies to so many people I know. Well, at least, it DID apply to them before they lost their McMansion and, in some cases, went bankrupt.
As I posted elsewhere: http://www.pewresearch.org/fact-tank/2015/07/16/are-you-in-t...
$80,000 USD / 4 people in America is the lower bound of high income.
That pew study is income relative to worldwide range, which is fairly pointless in this context. Nobody is talking about upper/middle class boundaries in these terms, and McMansions are largely a US (North American?) phenomena.
Any family in the US with a very low six figure household income (or even a very high five figure) can choose to finance a McMansion. They are not rich by US standards.
McMansions are an exercise in echoing certain features of the latter on the cheap, but they are primarily an embodiment of social positioning within the upper middle class.
