It’s a very common prolife trope. The world will collapse if not enough babies are born because the economy will collapse and there won’t be enough people to get work done.

For me, the truth of this statement is location dependent. In a place like Japan, yes, I could see some consequences of population decline. Such as not enough people to take care of the elderly.

On the other hand, there are undoubtedly positive effects such as the fact unemployment would likely plummet for at least a few decades, given that there isn’t a shortage of work today but rather not enough jobs for everyone.
