in many, many cultures, and for most of the history of euro-north american cultures, families always lived together. it seems odd to me that we are now thinking that this is unusual. quite frankly, with 2-working-parent families, it would be a lot easier if we still lived with, or at least near, mom and dad.
but we insist that it is not ok for adults to live with their parents, and so we send our kids to daycare, which costs as much as rent and puts the raising of kids into the hands of strangers.
i will do it myself, but i wonder all the time why.
