That may have an effect, but I don't think the root cause is the number of developers.
The root issue is that people and groups are disorganized and have inconsistencies between them. Changing habits and convincing other humans and making political coalitions is very hard, so instead people are willing to spend surprisingly large amounts of money in various ways that somehow take the edge off.
Creating or adopting software to "organize" is just one way that can occur. It could also be something like a doomed initiative that someone with clout wants, or even just paying the salary of a useless person hoping they'll leave on their own because firing them is too hard.
