I kind of took it as a thought experiment: what if everyone grew up with loving parents (and ideally a loving extended family), without painful divorces, without abuse of any form (sexual, physical, verbal), without neglect etc.. Then society would probably function better. But what if it was still messed up, no jobs or none paying enough to live off, abusive authoritarian structures etc. etc.. Then maybe such people would try harder to change their society for the better.
But it's kind of a moot point as we actually have to live in a world where people grow up in boatloads of way unideal situations and then enter a plenty dysfunctional world after that.
