Sounds like you're saying that people need to use their "personal time" in order to have and care for their children? I know you want to generalize and just give everyone personal time, but the net effect is that it would appear selfish as those that stand to benefit the most from such a restructuring would be the childless. It's not the equitable/fair middle-ground that you're proposing it to be in this case at all, hence why you're being downvoted.
