> But in the 1950s and 1960s, tens of millions of women traded their unpaid household management jobs for salaried jobs, and the family social calendar frayed

I don't think it was exactly a "trade". Women were still (and in some relationships still are) the household managers for the most part.

One notable difference: People were much more likely to have a maid, housekeeper, or nanny in 1950. About 1 in 25 households did then, in 1900 it was 1 in 13.

Another interesting thing is that I think the art of hosting is generational in a way. I grew up watching my parents have massive annual parties and friends over all the time. I learned from watching, and picked my apartment layout and arranged the furniture in it to optimize for comfortable conversation and seating for ~8-12 people. I like being the default host, I still have friends over for TTGs or video games a few times a month. Some people are just not good at getting their space comfortable for gatherings (or they don't offer guests drink / snacks). Or they turn it into a spotify jukebox thing where it's hard to talk over the speakers (or their soundtrack is annoying).
