820 ILCS 405/100
As a guide to the interpretation and application of this Act the public policy of the State is declared as follows: Economic insecurity due to involuntary unemployment has become a serious menace to the health, safety, morals and welfare of the people of the State of Illinois. Involuntary unemployment is, therefore, a subject of general interest and concern which requires appropriate action by the legislature to prevent its spread and to lighten its burden which now so often falls with crushing force upon the unemployed worker and his family. Poverty, distress and suffering have prevailed throughout the State because funds have not been accumulated in times of plentiful opportunities for employment for the support of unemployed workers and their families during periods of unemployment, and the taxpayers have been unfairly burdened with the cost of supporting able-bodied workers who are unable to secure employment. Farmers and rural communities particularly are unjustly burdened with increased taxation for the support of industrial workers at the very time when agricultural incomes are reduced by lack of purchasing power in the urban markets. It is the considered judgment of the General Assembly that in order to lessen the menace to the health, safety and morals of the people of Illinois, and to encourage stabilization of employment, compulsory unemployment insurance upon a statewide scale providing for the setting aside of reserves during periods of employment to be used to pay benefits during periods of unemployment, is necessary.
