For the 1/10 times at work where the person in power ends up having a meaningful relationship with an underling that you lose, you also have the 9/10 cases of sexual harassment that you lose too.
Needless to say, those are pretty big ifs.
I don't have a good answer for how to get the one without the other, but both are consequences of modern sensibilities.
In which case, the future belongs to societies where women don't work and birth control is stigmatized.
It could be that there is a reason why the world was dominated by large patriarchal societies other than some sort of accident of history.
If that's true, then a society with lots of gig jobs or work at home jobs might help alleviate the problem. There could be other creative solutions, like reimagining higher education to give people time to marry and have kids before college. Other approaches are also possible. Whatever the reason, the secular societies will need to scramble if they don't want the world of the future to be dominated by orthodox religious populations.
But I think in such ancient societies, the struggle is a little different. E.g. when you are being ravaged by wars and plagues, you need more than replacement level fertility. You need huge fertility that can recover massive population loss in a short period of time. After Hannibal decimated the population of Italy, Rome recovered remarkably quickly. They just made more Romans. Later on, that stopped working and they needed manpower from the provinces.
In modern societies, we've licked most of the other stuff and so can keep going much longer as fertility declines, to the point where we start noticing only when rates hit below replacement. Traditional societies would see population loss long before fertility rates fell below replacement.
This is essentially the advice of the "Princeton Mom": Find and marry your spouse in college. <https://www.today.com/popculture/marry-smart-princeton-mom-s...>
Even short of artificial wombs, there is a lot that can be done to help with this. The real issue isn't that women don't want to have kids at all, ever. It's that if they enter the labor force and work full time, usually it gets put off, often until it's not exactly too late, but at least too late to have as many children as you might have if you'd started earlier, bringing down the national birth rate because too many would-be mothers have aged out. There could easily be medical solutions to that focused on making pregnancy more viable in late middle-aged women. Better prenatal care, cheaper treatments for infertility. Even non-medically, it could just be more flexible working arrangements like you mentioned, work from home, better and cheaper daycare, more generous universal leave policies that don't single out parents, possibly something like sabbaticals that universities do but for commercial ventures, too. Mandatory paid gap years for people in their 30s even if they don't have children. A country that pulls that off could keep the economic advantage of having a larger workforce talent pool to draw from without sacrificing internal population growth.
Obviously, private employers can't bear that burden and it would need to be subsidized by the government, but if you really believe there would be significant national strategic advantages to doing this, then it should be subsidized by the government.
The hard truth is that it's not as expensive or complicated to encourage people having child but for some reason we are trying to do anything except for the things that actually matter: allowing parents that want to spend all their time with their new child this opportunity and allowing parents that can't be bothered to handle all the early mechanical aspects to avoid them.
Cheaper starter housing and for the US cheaper higher education would also help but I'm convinced those are lower priority than targeting the early years.
If a society is required to pay so much for something that used to come naturally through cultural forces, then it’s probably not sustainable.
So much? Singapore's GDP per capita is $60k per year so $5k per month. If $2 month's worth of GDP for 1 baby so an entire lifetime of a new citizen is a lot, then I don't even know what to say.

Having kids sucks (your mileage may vary, but before ~2-3 years the investment >>> benefits for all but the most dedicated people out there). Kids used to be cheap labor, which is now illegal for good reasons and they could be abused at will for various things, which is also illegal for good reasons. They were also frequently born because women didn't have a say in the matter, which is also becoming illegal for good reasons.
It is sustainable, it just needs to be done properly and respectfully.
Not by treating women like broodmares and kids as slaves to be worked to death and beaten up by adults who don't have any other way to relieve stress.
