This video covers chapter two, including an in-depth explanation of Figure 1 on page 48, with additional visual elements to help make it easier to understand.
Chapter Two is all about Keynesian objections to Austrian Business cycle, and Rothbard outlines a few of the more peculiar definitions that Keynesians use, and discusses why they cause trouble in economic reasoning.
Show notes here, but if you want the explanation of Figure 1, you’ll need to check the video starting at around 14 minutes in.
