We're well below replacement rates in most western and developed countries, there's a population crash expected in the next few decades which will cause issues as people age out and economies will shrink rapidly and social security programs will collapse, etc. The irony is, those far better equipped to have and raise intelligent productive kids, those with high education, good salaries, and liberal/progressive values, have less kids, meaning most kids in the next generation will be had by religiously conservative or less educated or poorer families and then these people will lament why their country is becoming more conservative when they don't have another generation they raised to pass their values onto. Which is counter productive if you want engineers and those that value the environment as a priority. For instance, Russia is expected to half their draft able males in the next 5 years and many of their educated engineers and technicians are older since they were mostly educated during USSR days, and be retiring age soon, which as reason why many think Russia is making moves now, while they still can. Shaming people for having kids is sheer idiocy at this point. Every person having 2 or more kids isn't even making up for the 5-10 people having 0-1 kids. The eventual conclusion of your reasoning, everyone is better off swallowing a bullet for the good of humanity.
