Walter Moss: We can grant that capitalism can have many beneficial effects and that other systems like socialism can have their defects, nevertheless the essence of capitalism is the selling of goods and services and making a profit, and it has no higher moral goal. Essentially an economic system, it provides no adequate answers for how to deal with such problems as unsafe working conditions, unfair business practices, pollution and other environmental degradation, public health, slum housing, or the abuse of child labor. This absence of any higher comprehensive social philosophy led to efforts to supplement it by providing an overall philosophy of the public good. This absence led to Progressivism.
