Nature's usual metric involves the chances of genes being ancestral.
If the female head of a university faculty has sacrificed her role
as a mother to get there, then her genes are probably not doing very
well in nature's eyes - unless perhaps she is contributing generously
to the welfare of her sisters.
However the "welfare queen" might not be doing much better. She
may be supporting several kids - but will any of them become long-term
ancestors? Nature is not interested in how many kids someone has -
but in whether there are great-great-grandchildren - and having lots
of kids and investing only a little in each one may not necessarily
be the best way of doing that.
The woman on welfare has one thing going for her, though - she has
got the government to sponsor her kids. Quite why the government
would do that seems rather mysterious, but - in my country at least -
the government often seems prepared to sponsor individual children -
and pay for their education out of everyone's taxes.
It's a bit like the genetic equivalent of an anti-robin hood -
they forcefully extract resources from those with no kids - and
give the proceeds to those who already have plenty of offspring.
I understand that - in America - that sort of thing does not go on.
