Serious thought/question: I think everyone can agree that reproduction is how you advance your gene pool to the next stage of the human species. Does this mean people who don't want kids are effectively weeding themselves out? And is this somehow a function of survival of the fittest (or natural selection) in action?

Yes, in theory all the people who refuse to reproduce will be gone and are replaced by the children of those who want to reproduce. Over the long term this problem will fix itself. However, I personally believe that the population will level out instead of keep shrinking forever until reproductive pressures fix the problem by force.

Those, who do want to reproduce, will also be replaced by the next generations. Natural selection doesn't select individuals, it selects genes. And your genes are well-represented in the rest of the population.
