I blame this on our fiat system. We went from having households with 1 parent working to 2 to 2 highly educated. Meanwhile, the prior generation are living longer and spending more. This puts a strain on our younger generation confidence in being able to support their children. When this goes on, it normalizes not having children.
I will raise my kids in a supported environment with the hopes that they realize the importance of having kids and are able to in their 20s.
