I don't think it's a great idea to apply Darwinism to fields outside of biology, especially in the social sphere. It led to a lot of bad science in the past.

It sure as hell seems like natural evolution is being applied to the social sphere. Statistically, children from "well off" families do consistently better across all life pillars (health, money, family, friends) than poorer families. Come on, financially richer families are less fat/obese than poorer families. This is a direct link to living and longevity (Darwinism).

Yes, but the two groups exist and are adapted to two totally different environments. I imagine that some in the well off population see the others as a different species. Thusly, strict Darwinism doesn't apply here.

To truly see who is more fit, I propose that we take a group of 12, 6 from each class, and drop them off on an uninhabited island. We will places weapons and traps at strategic locations. We shall call this experiment Project Craving Romp.

May the odds be ever in their favor!

It's pretty hard to say that human interaction is outside biology without invoking the metaphysical
