That leaves really only two choices: pull a Ceaușescu and try to remove the choice, or improve all of the things which make people feel now is not the right time to have kids. Since the former choice is both immoral and self-defeating, that really flips the discussion to why the people who claim to want more children oppose universal healthcare, childcare, making housing more affordable, banning negative career impacts for mothers, addressing climate change, etc. There are many things which factor into an expensive multi-decade bet and you have to improve all of them to substantially shift the outcome.
What does this actually mean? Do you mean "get a job instead of having kids?" Working to afford life instead of having kids seem much less humanising, if anything. Being a wife and mum is being a full person, and the main thing that's bad about it is if you are a full-time mum your spouse has to work incredibly hard to compete on the housing ladder against all the two-income families bidding against them.
Now, however, there are tons of other opportunities available. Instead of kids just happening, couples can plan them and are making decisions about their finances and other life impacts such as the case you mentioned where people might realize that they can’t afford a larger home. Prospective mothers, even if they really want kids, are also being told advanced education is key or that mothers tend to have lower lifetime earnings even adjusted for field, so the questions aren’t just “can we feed them?” but “would I avoid future layoffs if I finish a masters degree before becoming a parent?”
I think that’s great, everyone should control their life trajectory, but it means that to the extent we want to reverse the trend we need to be lowering the costs so people aren’t looking at trade offs like permanently lowering their career trajectory or locking themselves into a limited, highly-competitive corner of the housing market.
This was the case for most men as well, except they sometimes had to go and die weeping and in pain in a foreign field rather than stay at home and do what for most people is the most rewarding thing in life.
You need free time for kids and if the salaries are too low for a single income household a lot of people will end up opting out of having kids.
This isn't unique the the US. Basically every country with a whack work life balance is looking at population replacement problems.
The US is actually better off with replacement rate than a lot of countries that have industrialized since them because of the way it happened and the wars that were fought. More rapidly-industrializing countries (China, Japan, a few other Asian and SA countries) have way shorter runways despite industrializing much later than the US. And those with one child policies really just made things worse for themselves.
A very large part of what the future is going to look like in my opinion is how different countries are able to grapple with this issue and come up with solutions to the problem of a large aging population and a service, hospitality and medical industry with not enough bodies.
