But the opposite all too often results in a situation where family trees become power structures and that's how you time-travel back into the middle ages.
Extended family living, as was the norm for the vast majority of human history up until the mid 20th (and is still a fairly equal alternative in many parts of the world).
I would have thought the connection between the sequestering of nuclear families in single family homes and the dwindling of communal childcare/rise of expensive commercial childcare options to be fairly obvious.
