John Stuart Mill is an intellectual figure of the 19th century, became what he was by the strict upbringing of his father. He was interested in „anything and everything". He tried to reconcile utilitarianism of classical liberalism writers with social principles. He tried to write the book which will find practical application with the quality that will match "Wealth of Nations". He saw that raising the efficient structures must start with bringing down old parts of it, because the problems and tasks of public administration can not be solved without state interference. He considers laissez faire as a general rule for the management of economic of the country. Unlike Ricardo and Smith, he left the pessimism about the steady state. He continues with optimism also in Malthus`s population law. However, in the theory of wages, he considers that the total amount of capital must be intended for the payment of workers, with the known population and invested capital. It can not be changed except in the case of new investments in production or population increase. He was more pessimistic than Ricardo at it. Mill's work is strictly positivist framework, knowledge of his teachers that he tried to fit into the social and political thought of the future development.
