You may have caught the title’s little inside joke.
Sometimes you (well, I anyway) can look at a graph representing data that is a culmination of history (i.e. reality) and just let it settle in for some perspective and even some conclusions.
Whether these conclusions are right or wrong is subjective and open to debate. But what I see here when viewing the Prime Rate historical is summed up after the graph (graphs courtesy of Economagic, mark ups mine).
