That's one way of looking at things. Another is that countries like Japan are having huge issues because nobody is having kids anymore. Quantity of life matters, too.
But I agree that people should be wiser about planning their lives out. I'm not sure that's a solvable problem, though.

Eh, I think Japan's problem is more that they have a very narrow idea (ethnically speaking) as to what they want Japanese people to look like. If they were willing to loosen up a bit on that, there are plenty of people who would be willing to come, become Japanese, and if it's anything like immigration here in the US, probably have a fair number of children.
Or maybe being a heavily populated island nation is the root of their problems, both in terms of what kind of person they find acceptable and how many people can be tolerated in the limited space they have.
Japan will not survive in any real way, demographic numbers are such that whatever might survive will not look very much like Japan does now. They simply are not having enough kids, and have been on that path for a very long time with no sign of the dramatic change they would need to survive.
