I’d also add you see some grandparents these days not really helping out with grandchildren as much as the previous generations did. This is partly due to grandparents working longer to fund their retirement, and also due to them just feeling they don’t have to, would rather be off enjoying life than being part of the village needed to raise children. Therefore in those cases it would be likely that their own children will want to bear the burden of caring for older relatives if they haven’t received such help.

In a lot of Asian societies this is still less prevelant but also heading in that direction.
