In terms of evolution, we've had a fine explanation for non-reproductive fitness for the last 50 years, since Hamilon formalised the idea of inclusive fitness.

While she does describe this, to suggest that non-reproductive individuals require special evolutionary explanation is to mis-characterise evolutionary biology. Let's not pretend that it's a special case for the sake of those with an incomplete understanding of evolution. It all fits very well: marginal fitness gains of additional reproductive males (for a gene) decrease with the number of males, such that producing non-reproductive males could be more beneficial.
