It's not easier to bring up children. I would happily relocate to a traditional culture with fewer creature comforts, but where my neighbors would watch the baby if I came down with the flu. But in the absence of those helpful neighbors it's nice to have disposable diapers and electricity.
It raised an interesting point: Have our creature comforts been the cause of our massive alienation? We know that a big problem of living in the modern world is that we all feel so terribly alone and unimportant. So much so that chemists can't keep enough Prozac on the shelf.
Could it be that we have created this situation by making our individual, independent lives easier?
