"An economist is an expert who will know tomorrow why the things he predicted yesterday didn't happen"

This quote by Earl Wilson is an amusing way of pointing out the unpredictability of economics. It suggests that economists are often not able to properly predict the future, which their predictions might not always come true. This is due to the fact that economics is a complex field that is constantly altering and evolving. It is impossible to forecast the future with absolute certainty, and economic experts need to take into consideration a variety of factors when making predictions. The quote likewise recommends that economists are experts in their field, and are able to explain why their predictions did not come true. This is a crucial ability, as it enables economic experts to learn from their mistakes and improve their forecasts in the future. Eventually, this quote works as a pointer that economics is a complex and ever-changing field, which economists must be prepared to change their predictions accordingly.
