In my social circle, if you're inviting people over, then you need to satisfy:
1. Neat + Tidy house
2. Good food, and lots of it
Both take time, and not for tired parents.
(To be clear: These are not my expectations...)
It's certainly not like I remember it in the 80s, but still happens a lot, and my uninformed take is: "community" in the US was never that cohesive, it only took so much to make it fall apart.
