>I also don't think a declining population is a bad thing necessarily.
It's a terrible thing. Women are waiting until their 30's to have kids. A mother's age post-wall is directly correlated with autism, down syndrome, and other defects. You also face the economic problems that come with a declining population, such as losing your status as a world power. This will make you the subject of other nations, such as the hostile Saudi Arabians. You also wouldn't be able to retire in such a world where births decline. Retirees rely on society taking care of them, which wouldn't be feasible if the only workers were your autistic cousins.
