You can tell a person's height just by looking at them — unlike other examples, you don't need any advancement in DNA science for that.

That makes height an easy topic to talk about, but it's still challenging to think through the implications. If you can increase your child's height by 20% and thereby increase their likely income by 25% - is it morally right not to? Does it matter whether others can afford that intervention? Is it morally right not to fund public access to such interventions? Does the answer change if relative height is all that matters?

On height, that is already a reality.
