Just reinforcing NoMoreNicksLeft, this is definitely considered a right wing talking point in the US. On hearing about this leftists immediately jump to "you want to roll back the gains of feminism, keep women in the home, blah blah".
What we need is to rearrange culture and institutions so that women wish to have children young, and so that they are valorized or at least not penalized in terms of career prospects or lifetime earnings for doing so. In relation to men, but even more so in relation to women who choose not to have children.
I think I am miswording the question — I don’t care about fixing the trends. My worry us to be prepared for the case if we can’t fix the problem. Basically “how we can prepare society to live with less younger population?”.

I have no idea how to go about doing that.
