"The fit and the unfit, in all meaningful senses, are dying in the third world right next to each other. "
​
Do you honestly think there's no selection going on in cases where large numbers of people are dying, in situations where environmental selection pressures are strongest? That there isn't selection for disease resistance, thriftiness with food metabolism? There may not be an anti-genocide mutation coming around the corner anytime soon, but it seems preposterous to think that world-wide deaths are completely independent of fitness in "all meaningful senses".

"Survival of the fittest" just refers to whichever genes are currently successful at getting passed on. Unless you think that currently
​
a) everyone has a perfectly equal chance of reproducing, or that
​
b) the chance of reproducing is 100% completely independent of genetic concerns,
​
Then there's no reason to assume that there is no "survival of the fittest".
​
Which one (a or b) are you arguing for?
