If there is such a correlation (I didn't know there was) couldn't that just be due to people in wealthier countries generally being taller due to better nutrition? Most of the world's billionaire's couldn't double up as NBA players. I'm not saying I wish anyone to be short just so they can fit in a bus seat better, being tall is great, but not too tall, I don't want to be any taller than I am and wouldn't mind being a couple of inches shorter. Even washing the dishes can be a pain.
