We need to learn to take care of the ones who are already here before we start making more. That’s not open for debate.
Personally, I think the solution of “not enough kids” mirrors that of a law proposed decades ago: if a citizen votes in favor of going to war, they’re automatically drafted should war be declared.
Republicans/Conservatives the world over want abortion banned, right? Cool, you vote to ban it, you’re automatically added to a list to adopt children who cannot be aborted. The individual gets no say in when the adoption happens, they have no say in gender/ethnicity/etc, the government shows up, hands them a baby, and that’s now their child. Government can do weekly/regular checks to ensure the child is being raised well enough and that the parent is home enough to watch them. And no limit on how many kids end up in your lap, either.
Oh, that doesn’t work with your work schedule/life schedule/etc? Too bad, you wanted to save the unborn babies, now save them. You can’t afford 13 newborns all at once? Sure sounds like a you problem, since you didn’t support any of the things to make the lives of children better, like abortion/contraception/sex ed, childcare subsidies, school lunch programs, etc.
Problem solved: Conservative Christians get to save all the babies, people can still keep making them without fear of it hindering their lives, and the population continues to grow so the capitalist machine can be fed.
