I'm more concerned about the graph attributed to flatworldknowledge.lardbucket.org. I've lived on the internet long enough to know a shitposter when I see one and that's a whale of a URL that every fiber of my body says never to click. I know it is a logical fallacy to dismiss an entire argument simply by association with a crank, but that's my gut reaction to that post.
... I didn't even notice the name. That site is an archive of a collection of textbooks that were Creative Commons-licensed before 2012, dedicated to the memory of Aaron Swartz. Evidently https://2012books.lardbucket.org/books/beginning-economic-an... goes to the same place.
