The theory of Collective Capitalism was advanced by the American economist G. Means in the 1960’s.
 It was intended to overcome the failings of traditional capitalism, which failed so spectacularly in the 1930s.
 It rejects the principles put forward by Adam Smith, the notion of the "invisible hand" of market forces being self-correcting is not accepted.
 Therefore, the theory reflects the process of the capitalist socialization of production, but only in a distorted way.
 Japan's Collective Capitalism relies on cooperation, but ignores the determining fact that the ownership of the means of production is still private.
 It cannot be considered Socialist because the means of production does not belong to the individual, but rather, it belongs to the corporation, which ultimately aligns more strongly with traditional Capitalism.
