It's not better, because by the time people reach old age and understand the dangers of old age destitution and how dire is the lack of support from close family, they can't act on it anymore. Things need to be structured in a way people act while they still have opportunity.
One thing that makes me suspect the population crash will be much harder to fix than the previous population explosion, it's that there's no immediate fix. It takes ~20-30 years to raise a human being into a fully functional member of modern society, after the decision to conceive them was made. It's a long term investment. Back when people panicked on population explosion, some of the proposed "fixes" were brutal, like forced sterilization in India[1], or forced abortions in China[2], but they could be implemented and sometimes stopped quickly.
There's fundamental asymmetry. Time to terminate an unborn child is measured in hours to days (counting the recover time for the mother). Time to fully _raise_ a child is measured in decades. By the time people panic over it, it may be too late to avert the crisis.

More to the point, human's reproductive lifetime is usually about 30 years. So by the time you realize that you've fucked up your society, the cohort that could do something about it has now aged out of childbearing years. You're left with a much smaller cohort to fix the problem, but because there are now so many fewer women of childbearing age, increases in fertility rate lead to many fewer births.
This is actually happening with Millennials. Strauss and Howe predicted a "Crisis of 2020" that would lead to civic renewal and presumably a higher birth rate, but it now appears that 2020 was the beginning of the crisis and it won't be resolved for some time, perhaps a generation, and by that time Millennials (globally, the last big generation) will have aged out of childbearing years. Any baby boom will be led by late Zoomers, at best, and that's a small generation that's already affected by the collapse in birth rates.
My takeaway: the globalized, technologically advanced society we have now is doomed to collapse, and we should be working hard to take that advanced technology and identify simplified versions of it that can be run and maintained by a much smaller, localized workforce.
