Why would a poor man sire significantly fewer children than a rich man?
Polygamy might have tipped the balance of available mates in favor of
the rich and powerful, but otherwise war and other violence was tipping
the balance toward every man having an opportunity to mate (assuming
significant levels of monogamy). Nutrition and health care (and
stressors) might reduce the number of children a woman could (live)
birth and raise to reproductive age, but I don't think the bias is less
than 2:1 on average?

Does this mean you believe that wealth was a direct correlation to some
genetic feature? Within strict class and even more acutely, blue-blood
nobility/caste reproductive contexts, there is *some* correlation, but I
think the unrecognized effects of over-inbreeding did more harm than good?
I am willing to believe that high aggression may still have been
selected for reproductively up into the industrial age, but I think that
got sublimated into wealth and power collection more than reproductive
fecundity (though I grant up to 2:1 advantage *through* acquired
wealth). e.g Genghis hisself

With the ?8.6B? people on this planet, I suspect "if we can, someone
is/has/will". The previously linked article on Texas Ranchers cloning
prize Bucks suggests to me that up to the practical challenges imposed
by broad ethical concerns that human cloning has to be (nearly) as easy.

and we DO have the Raëlians <https://en.wikipedia.org/wiki/Ra%C3%ABlism>
and Clonaid. <http://www.clonaid.com/>

my kids are too much like me already, we can barely get along as it is!
