I'm certain this is the case with humans as well.

Growing up, I had a tight-knit group of four friends in a lower middle-class townhouse community. I think the enthusiasm we all brought to our childhood and embracing our diversity (all four of us were completely different races) helped us all excel as adults. It's been 15-20 years since college, but I remember how socially underdeveloped many of my peers were. Almost two decades since then, it's not a surprise to anyone that the more socially and emotionally in-tune people climb their industries faster.
