By died out I meant the household aspect is gone, the original meaning included things like paying a carpenter to fix your roof which just seems like an alien use of the term. https://en.wikipedia.org/wiki/Oeconomicus https://en.wikipedia.org/wiki/Oeconomicus Outside any transaction playing a role in the overall economy.

Meaning people talking about the economy being good because they got a raise isn’t referring to household budgets but the wider economic system.
