I think there's two shifts that play a major role in explaining the timing that you're referencing:

- The 2010s represented a progressivist left-ward shift in America and the excesses of that movement are provoking a reactionary conservative shift in the populace in the 2020s: https://www.noahpinion.blog/p/seven-reasons-america-is-heade.... This is cyclical is the same thing happened from 1960s to 1970s.

- The concept of population collapse entered mainstream discourse in the early 2020s and is now being accepted as the major concern for humanity moving forward, a 180-degree turn from the previous concern of overpopulation. This is something unprecedented in human history as no human has ever existed in an economy or society where the population was decreasing so all the "rules" we know about life are suddenly subject to change unless birth patterns change significantly.
