This criterion indicates how many times the performed path of work is more thanthe defective part. This criterion was called quality factor. It is found out correlation between the HumanDevelopment Index and quality factor. It is shown that, as the quality factor increases, the level of public interestincreases, the level of individual interests decreases and prosperity increases. Democratic thinking replacesadministrative thinking. The author believes that humanity is developing in the direction of public interest and thehistory of humanity is the history of public interest.
