I agree with you about how we probably haven’t reached the point where the governments are supposed to worry, but I don’t think looking at a point in time in the past is right. Even though we have a long way to go for the decline to reach the population levels of 1950s, the demographic pyramid is pretty much inverted. Same applies to China and South Korea in some degree. Most of the women after the age of 40 aren’t going to have a kid, yet alone 2.1+ to revert the population decline.

But you’re right, more drastic measures will be taken in political and economical senses once absolute numbers start ramping up. It’s fairly obvious our current system isn’t the best for aging population with not as many children. Unfortunately, we just haven’t come up with anything better that gives some sort of stability and peace.
