> Because society as a whole hasn't spent hundreds of years literally enslaving short people Actually, they have done exactly that. For many centuries before appropriate nutrition became essentially ubiquitous, there was indeed a highly-significant correlation between height and social class - and the lowest class often faced near-slavery conditions in surprisingly recent times, especially outside Western Europe. Of course, you're right that "strict moral and legal standards" are rather lacking on the issue. I'm not sure that we would agree on whether that's a desirable state of affairs.
