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.
