Implicitly, the capacity utilization rate is also an indicator of how efficiently the factors of production are being used. Much statistical and anecdotal evidence shows that many industries in the developed capitalist economies suffer from "chronic" excess capacity. Critics of market capitalism, therefore, argue the system is not as efficient as it may seem, since at least 1/5 more output could be produced and sold, if buying power was better distributed. However, a level of utilization somewhat below the maximum typically prevails, regardless of economic conditions.
