43 Pa. Stat. § 752
Economic insecurity due to unemployment is a serious menace to the health, morals, and welfare of the people of the Commonwealth. Involuntary unemployment and its resulting burden of indigency falls with crushing force upon the unemployed worker, and ultimately upon the Commonwealth and its political subdivisions in the form of poor relief assistance. Security against unemployment and the spread of indigency can best be provided by the systematic setting aside of financial reserves to be used as compensation for loss of wages by employes during periods when they become unemployed through no fault of their own. The principle of the accumulation of financial reserves, the sharing of risks, and the payment of compensation with respect to unemployment meets the need of protection against the hazards of unemployment and indigency. The Legislature, therefore, declares that in its considered judgment the public good and the general welfare of the citizens of this Commonwealth require the exercise of the police powers of the Commonwealth in the enactment of this act for the compulsory setting aside of unemployment reserves to be used for the benefit of persons unemployed through no fault of their own.
