You are making a mistake in thinking the aforementioned genetic variation “enables people to get by on less”. They just literally sleep less. I have a brother in law with this, and it’s a bit annoying for him as his wife needs the normal 8 hours a night. He cannot sleep 7-8 hours, only 6. He just reads in the bed for 2 hours a night. If he has too much to do, he skimps like we all do, but for him this is 4 hours a night during the week (needing to catch up on the weekend).

Other than sleeping less than others, he’s regular in every way. Very successful engineer, if it helps, certainly requires “deep thought” on the regular.

It is unfair, but so many genetic advantages are equally unfair.
