Television's "The Brady Bunch" depicted an upper-middle-class household with a live-in maid and a nice house in an LA suburb that did not otherwise live extravagantly by the standards of a decade or two later, when basically no one in the US except maybe the out-of-sight-rich had live-in help any more.
They were using very fast and loose definitions of both economics and physics on that show. That house only has 3 bedrooms in reality and no basement, pretty typical for LA home specs unless you are looking at the old money neighborhoods like Hancock Park where some of the homes look a lot more like the rich people's homes out east (albeit on much smaller lots).
Yeah, television, so a big grain of salt. The point is they were depicted as having a live-in maid, which was going away in the US at the time but still not nearly as remarkable in 1969 as it would be by 1980 or 1990. Or today.
The house was depicted as nice and up-to-date but not extravagant - the kids shared rooms, right? I was implying that another thing that's changed is that that house would cost a much larger multiple of income today than in 1969.
Otherwise they weren't depicted as living as extravagantly as a lot of comfortable people do today. No luxury cars, fancy vacations, etc. Marcia and Greg weren't flying to Africa or the Caribbean to do charity work for their college applications like plainly middle-class kids will do today. Mrs. Brady doesn't chew Alice out for buying tomatoes from Safeway instead of organic heirloom tomatoes at Whole Foods. All that would have been absurd in 1969.
