The problem isn't the retards and bydlo breeding ike rabbits so much as the rest of us are not. My whole family is college educated and none of us had kids, with it looking increasingly unlikely for all of us.
People always like to talk about the negative eugenics but they never think of pro-eugenics. Why would we not just offer incentives to good people to breed instead? Off doctors, diplomats, Polish game developers, intellectuals huge tax incentives to have kids, and after the second kid the State pays you to have more. Set up batteries of tests and make it a felony punishable by sterilization to cheat. Let wealth not buy it because Lord knows there's some complete fucking idiots and useless sacks of flesh walking around this country with tons of money and we don't need that breeding either, which I suppose is also interestingly telling that class is someehat divorced from wealth here, or at least intellect. We should make life as easy as possible for decent, intelligent people to breed prolifically because at the end of the day, if you sterilize a bunch of stupid people and assholes the world is still full of other stupid people and assholes and those decent intelligent people still aren't breeding.
I guess the worst case apocalypse scenario could be simply drug and increase the flow of alcohol/other drugs into higher IQ/successful people and deny them birth control. Or/and start huge fearmongering media campaigns in bydlo communities about cockrot if you don't wear a condom. Start rumours among kids kids are stupid. Although I guess on some level we have a bit of this now with the anti-vaxxers but it's not killing them off fast enough.
