@frphank imagine you are measuring your nephew’s height. He is a healthy young lad visibly progressing well. Your ruler uses cm or inches - whatever your preference is. All of a sudden the international society of ruler central planners decree that today’s cm/inches are 40% smaller than yesterday’s cm/inches. Did your nephew grow 40% in height overnight? This is fiat central planning in a nutshell. All economic calculation is persistently and periodically rugged.
