Amartya's article sighted by Pearce is about 100 million women population deficit because of natural selections Genetic and Biological differences favoring male birth numbers.
We're way off topic. But that's just what it doesn't say (at least, after the first sentence).
The cited article eloquently sets out why the numbers are exactly not what would be expected by genetic and biological differences alone. To quote:
"These numbers tell us, quietly, a terrible story of inequality and neglect leading to the excess mortality of women."
It's hard to reconcile the heady writing of Nobel Laureates with seedy goings on in San Pedro night clubs. But I felt I had to set the record straight on an important piece of writing.
