Pretty sure author is being tongue-in-cheek, but I went and checked and that's the maximum range of the job-postings-by-indeed dataset (Early 2020 to present) so it's not possible to do a longer-term comparison. [0]
This is unfortunate since the other chart [1] has more history and some interesting changes right-before-then, which could have either helped confirm or explode this correlation.
That said we don't have to look at "job postings", what about actual employment? That's a lot more even-keeled and boring looking. [2]
