It is true that metrics such as stock market performance, economic growth, and employment numbers can be easily gamed, and that retail investors are often duped by these metrics. However, this doesn't mean that these metrics should be completely abandoned. Although they are imperfect and may be manipulated, they can still provide useful information and insights into the overall health of the economy. For example, stock market performance can be a good indicator of investor confidence and economic growth can provide an indication of the overall direction of the economy. Additionally, employment numbers can be a useful tool in understanding labor market trends and the health of the job market. While these metrics may not be perfect, they can still be useful in providing an overall picture of the economy and helping investors make informed decisions.
