TBH it was also expected trade - you will take care of elderly parents in exchange for their help with kids participation, so since boomer parents don't help they also can't expect help
my (divorced) parents (5+ and 2.5+ hours away by car) didn't help us with kids at all (wife's parents are 7500 km away), but they can't expect I will be taking care of them when they will be really old, after all my father and his sister put their own mother to retirement home, when she could not live alone by herself, so they should kinda expect the same treatment (although I was against it and wanted grandma rather die alone in her house earlier than suffer slightly longer in retirement home without her garden/animals), actually my mother put her mother to retirement home as well, though I think she wanted to go there, it was pretty great facility, it was very small house (studio), each separated part had one occupant with minigarden with meals minutes away + it was also <1km from her old big house, so not much change and not much difference for her since she lived in front of the living room TV anyway
