It's got to be cultural, right? In humanity's case... Anyway, my personal opinion isn't so much about long-term outcomes. Those seem almost wholly determined by genetics, anyway. It's instead a question of-- How happy is the child? How much do they enjoy life? I feel like that's a question which researchers tend to miss, and/or assume doesn't matter -- perhaps because it's harder to measure -- but isn't enjoyment of life the entire goal, in the first place? And childhood is a significant fraction of life.
