That's mistaking the scientific theory of evolution as we define it today for something that it isn't. I'm not making value-statements about anyone's contributions to society, because it's unrelated to modern evolutionary science. I agree people have a lot more to contribute to society than whether they have children or not. It would be patently silly to suggest otherwise. I admire a great many people who didn't or won't have any! It won't change that your hypothetical redneck passes on more genetic material than they do.
