That would be fine if the article was called "Japanese people don't start enough families" - however, this wouldn't be an interesting headline, since it's years old news and most informed people know this already[1]. But it isn't, is it? It's asking the question why. I can ask such questions as well, but if I'm going to write an article about it, I'd hope to come up with some analysis to try to answer it - and this is exactly where the journalist got lazy and just cobbled up whatever anecdotes he can attribute to actual Japanese people saying them, cause, you know, they must be at the source of this, right? [1] Although I'm not yet sure whether more babies is actually what Japan needs right now - looking at their population density, going easy on the baby making might be ok for a while, if there is a plan in place on how to turn it around once the population has fallen to more sustainable levels (and also how to pay for everyone's pensions in the meantime).
