Abortion and birth control are important tools in the ultimate human thriving toolkit.
Unless you want to eliminate all the robots and go back to agricultural labor (which is not going to get you an interstellar society,) you will have to deal, somehow, with all of the humans who don’t have the chops to survive in society. Letting people starve in the streets is inhumane and inspires people to fund large social welfare states, which may have negative long-term effects.
Historically, death rates were very high, especially infant mortality. My great-great grandparents lost over half of their 16 children before the age of five; such was normal.
The effects of declining infant mortality are happy parents, of course, but also long-term degradation of the gene pool, overpopulation, and eventual systemic collapse as we burn through the Earth’s resources. We’re already seeing this, both in increasing reaction times (it looks like Whites are getting dumber, and Ashkenazi IQ is probably plummeting, relatively speaking,) and the flooding of high-breeding peoples out of their exhausted biomes into fresh territory to consume (to the detriment of those trying to maintain a non-degraded biome.)
As I believe I have mentioned before, there is nothing like a parenting forum to convince you that parents are idiots. Unfortunately, a very large percentage of people become parents because they are too dumb not to.
I recently had a conversation with a friend who tried to reassure me that this was not a problem. “Don’t worry,” they said. “Dumb people have always had more kids than smart people.”
“No,” I said. “No no no. Dumb people did not historically have more kids than smart people.” History was brutal; 20-50% infant mortality was the norm, and people who did a better job taking care of and providing for their children had more children who made it to adulthood than those who didn’t.
No one in their right mind wants to simply eliminate all maternal and childhood medical care (and hygiene) so we can return to the age of high infant mortality. There are far better solutions than giving everyone Smallpox and seeing who makes it. But you also do not want a situation where the primary barrier to reproduction is actually intelligence.
The obvious solution is free IUDs for everyone. Globally. The long-term planners will get theirs removed when they’re ready to have children, and the short term planners will be able to go about their business without making “oopsies.” People who want 18 children will still be able to have 18 children, but people who don’t have the resources to support children don’t have to have any.
Abortion also plays an important role in the maintenance of modern society. Ideally, free abundant birth control would eliminate most of the need for abortion, but there will always be mistakes, medical complications, and non-viable fetuses of various sorts. Eliminate these earlier, not later.
These are not the children of intelligent, healthy, well-adjusted people who have some weird phobia of childbirth. These are fetuses with health problems and fetuses whose parents don’t have the resources, mentally or physically, to take care of them. The apple does not fall far from the tree, and genetically, those children will inherit their parents’ traits. If you are not volunteering to raise those fetuses (and their fetuses) yourself, then I think you should give some serious thought to who you think will.
After all is said and done, I don’t care what Planned Parenthood does with aborted fetuses, so long as they’re disposed of hygienically. They’re already dead, for goodness sakes.
