As he originally explained it: "Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes." Metrics of GDP, inflation, and employment are commonly used in macroeconomics to approximate quality of life, but they're subject to the same problem. For instance, you may be able to increase GDP and employment by increasing violent criminality, expanding the markets for private security, insurance, weapons and prisons, but harming general quality of life.
