It's still very difficult to raise a baby on your own and even with two people. It will still feel like someone's career is harder to manage with a child, and so I don't think these things are really going to make much difference for the average person that will likely not be able to afford these things anyway. A committed married couple having children at a healthy age, feeding them well, and keeping them safe are going to still perform extraordinarily well against what you've laid out, and will likely also have higher happiness levels.
