from the 2015 data set via https://www.census.gov/programs-surveys/ahs.html https://www.census.gov/programs-surveys/ahs.html : out of 118.29 million housing units, 80.8m (68%) have dishwashers, 97.6m (82%) have washing machines, and 95.7m (81%) have dryers. For the grandparent: 105m (89%) have AC, and 112m (94%) have a furnace or heat pump or water/steam heat or built-in electric heat of some sort. All of those numbers would qualify as "most". Looking at the oldest stats I can find for each of those categories: 1970 -- out of ~75.3 million housing units, 35.3m (47%) have AC, and 62.6m (83%) have a furnace or heat pump or water/steam heat or built-in electric heat of some sort. 1985 -- out of 99.9 million units, 42m (42% heh) had dishwashers, 67m (67%) had washing machines, and 58m (58%) had clothes dryers. So 26% more homes have dishwashers, 15% more have washing machines, 23% more have dryers, 42% more have AC, and 11% more have better heating systems compared to the earliest data I was able to find. Point being, there's been a significant increase in the availability of many important in-house amenities over the last 50 years. Not that everyone has every amenity, but a lot more people have them, and that definitely affects the way we should interpret stats relating to housing costs.
