I would argue no-fault divorce is at least as responsible as social pressures. When someone can walk away with half + alimony + 20% child support even if they were at fault for breakdown of the marriage (i.e. adultery or abandonment) there may be a big incentive for them to do things destructive to the marriage for a payout.
