I SHOULD like to report the discovery of a remarkably high correlation between national levels of anxiety and economic growth rates. The discovery was made as a result of the following train of reasoning. The rate of economic growth of a nation is the rate at which it is getting richer. Many factors may influence this rate, but there is fairly widespread agreement among economists that one is probably the efficiency of the population as a working force. Obviously a nation with an efficient working force is likely to create wealth more rapidly than one whose working force is less efficient.
